Video game music is any of the musical pieces or soundtracks and background musics found in video games. It can range from a simple synthesizer tune to an orchestral piece, usually such that the older the game, the simpler the music. In recent times, many games have had complex soundtracks similar to those of movies, and sometimes even interactive soundtracks which change in order to create an appropriate atmosphere, based on what the player does. It is also common for video game soundtracks to be commercially sold or performed in concerts that focus on video game music.^[1] Music can also be an important gameplay element in certain types of video games (like rhythm games).

At the time video games emerged as a form of entertainment in the 1970s (the first generation), music was stored on physical medium in analog waveforms such as compact cassettes and phonograph records. Such components were expensive and prone to breakage under heavy use making them less than ideal for use in an arcade cabinet, though in rare cases, they were used (Journey). A more affordable method of having music in a video game was to use digital means, where a specific computer chip would change electrical impulses from computer code into analog sound waves on the fly for output on a speaker. Sound effects for the games were also generated in this fashion.

While this allowed for inclusion of music in early arcade video games, it was usually monophonic, looped or used sparingly between stages or at the start of a new game, such as the Namco titles Pac-Man (1980) composed by Toshio Kai or Pole Position (1982) composed by Nobuyuki Ohnogi.^[2] An early example of video game music was the opening tune in Tomohiro Nishikado's Gun Fight (1975).^[3] The first game to use a continuous background soundtrack was Tomohiro Nishikado's Space Invaders, released by Taito in 1978. It had four simple chromatic descending bass notes repeating in a loop, though it was dynamic and interacted with the player, increasing pace as the enemies descended on the player.^[4] The first video game to feature background music was Rally-X, released by Namco in 1980, featuring a simple tune that repeats continuously during gameplay.^[5] The decision to include any music into a video game meant that at some point it would have to be transcribed into computer code by a programmer, whether or not the programmer had musical experience. Some music was original, some was public domain music such as folk songs. Sound capabilities were limited; the popular Atari 2600 home system, for example, was capable of generating only two tones, or "notes", at a time.

As advances were made in silicon technology and costs fell, a definitively new generation of arcade machines and home consoles allowed for great changes in accompanying music. In arcades, machines based on the Motorola 68000 CPU and accompanying various Yamaha YM programmable sound generator sound chips allowed for several more tones or "channels" of sound, sometimes eight or more. The earliest known example of this was Sega's 1980 arcade game Carnival, which used an AY-3-8910 chip to create an electronic rendition of the classical 1889 composition "Over The Waves" by Juventino Rosas.^[6] Konami's 1981 arcade game Frogger introduced a dynamic approach to video game music, using at least eleven different gameplay tracks, in addition to level-starting and game over themes, which change according to the player's actions. This was further improved upon by Namco's 1983 arcade game Dig Dug, where the music stopped when the player stopped moving.^[7] Dig Dug was composed by Yuriko Keino, who also composed the music for other Namco games such as Xevious (1982) and Phozon (1983).^[2]

Home console systems also had a comparable upgrade in sound ability beginning with the ColecoVision in 1982 capable of four channels. However, more notable was the Japanese release of the Famicom in 1983 which was later released in the US as the Nintendo Entertainment System in 1985. It was capable of five channels, one being capable of simple PCM sampled sound. The home computer Commodore 64 released in 1982 was capable of early forms of filtering effects, different types of waveforms and eventually the ability to play 4-bit samples on a fourth sound channel. Its comparatively low cost made it a popular alternative to other home computers, as well as its ability to use a TV for an affordable display monitor.

Approach to game music development in this time period usually involved using simple tone generation and/or frequency modulation synthesis to simulate instruments for melodies, and use of a "noise channel" for simulating percussive noises. Early use of PCM samples in this era was limited to short sound bites(Monopoly), or as an alternate for percussion sounds (Super Mario Bros 3). The music on home consoles often had to share the available channels with other sound effects. For example, if a laser beam was fired by a spaceship, and the laser used a 1400 Hz tone, then whichever channel was in use by music would stop playing music and start playing the sound effect.

The mid-to-late 1980s software releases for these platforms had music developed by more people with greater musical experience than before. Quality of composition improved noticeably, and evidence of the popularity of music of this time period remains even today. Composers who made a name for themselves with their software include Nobuo Uematsu (Final Fantasy), Koji Kondo (Super Mario Bros., The Legend of Zelda), Koichi Sugiyama (Dragon Quest),^[8] Miki Higashino (Gradius, Yie-Ar Kung Fu, Teenage Mutant Ninja Turtles), Hiroshi Miyauchi (Space Harrier, Hang-On, Out Run), Rob Hubbard (Monty On the Run, International Karate), Hirokazu Tanaka (Metroid, Kid Icarus, EarthBound), Martin Galway (Daley Thompson's Decathlon, Stryker's Run, Times of Lore), Yuzo Koshiro (Dragon Slayer, Ys, Shinobi, ActRaiser, Streets of Rage), Mieko Ishikawa (Dragon Slayer, Ys), and Ryu Umemoto (visual novels, shoot 'em ups). By the late 1980s, video game music was being sold as cassette tape soundtracks in Japan, inspiring American companies such as Sierra, Cinemaware and Interplay to give more serious attention to video game music by 1988.^[9]

Near the end of the life-cycle of the Famicom, some game producers at their own expense custom manufactured their cartridges with an additional tone generating chip. These chips added to the existing sound chip in the Famicom, but also sported extra features to modulate the additional channels.

Early digital synthesis and sampling[link]

From around 1980, some arcade games began taking steps toward digitized, or sampled, sounds. Namco's 1980 arcade game Rally-X was the first known game to use a digital-to-analog converter (DAC) to produce sampled tones instead of a tone generator.^[6] That same year, the first known video game to feature speech synthesis was also released: Sunsoft's shoot 'em up game Stratovox.^[5] Around the same time,^[10] the introduction of frequency modulation synthesis (FM synthesis), first commercially released by Yamaha for their digital synthesizers and FM sound chips, allowed the tones to be manipulated to have different sound characteristics, where before the tone generated by the chip was limited to the design of the chip itself. Konami's 1983 arcade game Gyruss utilized five synthesis sound chips along with a DAC, which were partly used to create an electronic rendition of J. S. Bach's Toccata and Fugue in D minor.^[11]

Beyond arcade games, significant improvements to personal computer game music were made possible with the introduction of digital FM synth boards, which Yamaha released for Japanese computers such as the NEC PC-8801 and PC-9801 in the early 1980s, and by the mid-1980s, the PC-8801 and FM-7 had built-in FM sound. This allowed computer game music to have greater complexity than the simplistic beeps from internal speakers. These FM synth boards produced a "warm and pleasant sound" that musicians such as Yuzo Koshiro and Takeshi Abo utilized to produce music that is still highly regarded within the chiptune community.^[12] The widespread adoption of FM synthesis by consoles would later be one of the major advances of the 16-bit era, by which time 16-bit arcade machines were using multiple FM synthesis chips.^[10]

One of the earliest home computers to make use of digital signal processing in the form of sampling was the Commodore Amiga in 1985. The computer's sound chip featured four independent 8-bit digital-to-analog converters. Developers could use this platform to take samples of a music performance, sometimes just a single note long, and play it back through the computer's sound chip from memory. This differed from Rally-X in that its hardware DAC was used to play back simple waveform samples, and a sampled sound allowed for a complexity and authenticity of a real instrument that an FM simulation could not offer. For its role in being one of the first and affordable, the Amiga would remain a staple tool of early sequenced music composing, especially in Europe.

The Amiga offered these features before other competing home computer platforms. The Amiga's main rival, the Atari ST, sourced the Yamaha YM2149 Programmable Sound Generator (PSG). Compared to the in-house designed Amiga sound engine, the PSG could only handle 1 channel of sampled sound, and needed the computer's CPU to process the data for it. This made it impractical for game development use until 1989 with the release of the Atari STE which used DMA techniques to play back PCM samples at up to 50 kHz. The ST however remained relevant as it was equipped with a MIDI controller and external ports. It became the choice of by many professional musicians as a MIDI programming device.

IBM PC clones in 1985 would not see any significant development in multimedia abilities for a few more years, and sampling would not become popular in other video game systems for several years. Though sampling had the potential to produce much more realistic sounds, each sample required much more data in memory. This was at a time when all memory, solid state (cartridge), magnetic (floppy disk) or otherwise was still very costly per kilobyte. Sequenced soundchip generated music on the other hand was generated with a few lines of comparatively simple code and took up far less precious memory.

Arcade systems pushed game music forward in 1984 with the introduction of FM (Frequency Modulation) synthesis, providing more realistic sounds than previous PSGs. The first such game, Marble Madness used the Yamaha YM2515 FM synthesis chip.^[13]

As home consoles moved into the fourth generation, or 16-bit era, the hybrid approach (sampled and tone) to music composing continued to be used. In 1988 the Sega Mega Drive (Sega Genesis in the US) offered advanced graphics over the NES and improved sound synthesis features (also using a Yamaha chip, the YM2612),^[14] but largely held the same approach to sound design. Ten channels in total for tone generation with one for PCM samples were available in stereo instead of the NES's five channels in mono, one for PCM. As before, it was often used for percussion samples, or "drum kits" (Sonic the Hedgehog 3). The 16-bit Sega referred to was the CPU and should not be confused with 16-bit sound samples. The Genesis did not support 16-bit sampled sounds. Despite the additional tone channels, writing music still posed a challenge to traditional composers and it forced much more imaginative use of the FM synthesizer to create an enjoyable listening experience. The composer Yuzo Koshiro utilized the Mega Drive/Genesis hardware effectively to produce "progressive, catchy, techno-style compositions far more advanced than what players were used to" for games such as The Revenge of Shinobi (1989) and the Streets of Rage series, setting a "new high watermark for what music in games could sound like."^[15] Another important FM synth composer was the late Ryu Umemoto, who composed music for many visual novels and shoot 'em ups during the 1990s.^[16]

As cost of magnetic memory declined in the form of diskettes, the evolution of video game music on the Amiga, and some years later game music development in general, shifted to sampling in some form. It took some years before Amiga game designers learned to wholly use digitized sound effects in music (an early exception case was the title music of text adventure game The Pawn, 1986). By this time, computer and game music had already begun to form its own identity, and thus many music makers intentionally tried to produce music that sounded like that heard on the Commodore 64 and NES, which resulted in the chiptune genre.

The release of a freely-distributed Amiga program named Sound Tracker by Karsten Obarski in 1987 started the era of MOD-format which made it easy for anyone to produce music based on digitized samples. MOD-files were made with programs called "trackers" after Obarski's Sound Tracker. This MOD/tracker tradition continued with PC computers in 1990s. Examples of Amiga games using digitized instrument samples include David Whittaker's soundtrack for Shadow of the Beast, Chris Hülsbeck's soundtrack for Turrican 2 and Matt Furniss's tunes for Laser Squad. Richard Joseph also composed some theme songs featuring vocals and lyrics for games by Sensible Software most famous being Cannon Fodder (1993) with a song "War Has Never Been So Much Fun" and Sensible World of Soccer (1994) with a song "Goal Scoring Superstar Hero". These songs used long vocal samples.

A similar approach to sound and music developments had become common in the arcades by this time and had been used in many arcade system boards since the mid-1980s.^[17] This was further popularized in the early 1990s by games like Street Fighter II (1991) on the CPS-1, which used voice samples extensively along with sampled sound effects and percussion. Neo Geo's MVS system also carried powerful sound development which often included surround sound.

The SNES (1990) brought digitized sound to console games.

The evolution also carried into home console video games, such as the release of the Super Famicom in 1990, and its US/EU version SNES in 1991. It sported a specialized custom Sony chip for both the sound generation and for special hardware DSP. It was capable of eight channels of sampled sounds at up to 16-bit resolution, had a wide selection of DSP effects, including a type of ADSR usually seen in high end synthesizers of the time, and full stereo sound. This allowed experimentation with applied acoustics in video games, such as musical acoustics (early games like Castlevania IV, F-Zero, Final Fantasy IV, Gradius III, and later games like Chrono Trigger), directional (Star Fox) and spatial acoustics (Dolby Pro-Logic was used in some games, like King Arthur's World and Jurassic Park), as well as environmental and architectural acoustics (Zelda III, Secret of Evermore). Many games also made heavy use of the high quality sample playback capabilities (Super Star Wars, Tales of Phantasia). The only real limitation to this powerful setup was the still-costly solid state memory. Other consoles of the generation could boast similar abilities yet did not have the same circulation levels as the SNES/SFC. The Neo-Geo home system was capable of the same powerful sample processing as its arcade counterpart, but was several times the cost of a SNES. The Mega-CD (Sega-CD in the US) hardware upgrade to the Mega Drive (Genesis in the US) offered multiple PCM channels, but they were often passed over instead to use its capabilities with the cd-rom itself.

Popularity of the SNES and its software remained limited to regions where NTSC television was the broadcast standard. Partly because of the difference in frame rates of PAL broadcast equipment, many titles released were never redesigned to play appropriately and ran much slower than originally intended, or were never released. This showed a divergence in popular video game music between PAL and NTSC countries that still shows to this day. This divergence would be lessened as the fifth generation of home consoles launched globally, and as Commodore began to take a backseat to general purpose PCs and Macs for developing and gaming.

Though the Sega-CD/Mega-CD, and to a greater extent the PC Engine in Japan, would give gamers a preview of the direction video game music would take in streaming music, the use of both sampled and sequenced music continues in game consoles even today. The huge data storage benefit of optical media would be coupled with progressively more powerful audio generation hardware and higher quality samples in the Fifth Generation. In 1994, the CD-ROM equipped PlayStation supported 24 channels of 16-bit samples of up to 44.1 kHz sample rate, samples equal to CD audio in quality. It also sported a few hardware DSP effects like reverb. Many Square titles continued to use sequenced music, such as Final Fantasy 7, Legend of Mana, and Final Fantasy Tactics. The Sega Saturn also with a CD drive supported 32 channels of PCM at the same resolution as the PSX. In 1996, the Nintendo 64, still using a solid state cartridge, actually supported an integrated and scalable sound system that was potentially capable of 100 channels of PCM, and an improved sample rate of 48 kHz. Games for the N64, because of the cost of the solid state memory, typically had samples of lesser quality than the other two however, and music tended to be simpler in construct.

The more dominant approach for games based on CDs, however, was shifting toward streaming audio.

MIDI on the PC[link]

The first developers of IBM PC computers neglected audio capabilities (first IBM model, 1981).

In the same timeframe of late 1980s to mid 1990s, the IBM PC clones using the x86 architecture became more ubiquitous, yet had a very different path in sound design than other PCs and consoles. Early PC gaming was limited to the PC speaker, and some proprietary standards such as the IBM PCjr 3-voice chip. While sampled sound could be achieved on the PC speaker using pulse width modulation, doing so required a significant proportion of the available processor power, rendering its use in games rare.

With the increase of x86 PCs in the market, there was a vacuum in sound performance in home computing that expansion cards attempted to fill. The first two recognizable standards were the Roland MT-32, followed by the AdLib sound card. Roland's solution was driven by MIDI sequencing using advanced LA synthesizers. This made it the first choice for game developers to produce upon, but its higher cost as an end-user solution made it prohibitive. The AdLib used a low-cost FM synthesis chip from Yamaha, and many boards could operate compatibly using the MIDI standard.

The AdLib card was usurped in 1989 by Creative's Sound Blaster, which used the same Yamaha FM chip in the AdLib, for compatibility, but also added 8-bit 22.05 kHz (later 44.1 kHz) digital audio recording and playback of a single stereo channel. As an affordable end-user product, the Sound Blaster constituted the core sound technology of the early 1990s; a combination of a simple FM engine that supported midi, and a DAC engine of one or more streams. Only a minority of developers ever used Amiga-style tracker formats in commercial PC games, (Unreal) typically preferring to use the MT-32 or AdLib/SB-compatible devices. As general purpose PCs using x86 became more ubiquitous than the other PC platforms, developers drew their focus towards that platform.

The last major development before streaming music came in 1992: Roland released the first General MIDI card, the wavetable SCC-1. The comparative quality of the samples on the wavetable spurred similar offerings from Soundblaster, but costs for both products were still high. Both companies offered 'daughter board' wavetables that could be later added to a less expensive soundcard (which only had a DAC and a MIDI controller) to give it the features of a fully integrated card. (Roland had used a similar interchangeable daughterboards in its musical instrument keyboards, also widely used to develop music at the time.)

Unlike the standards of Amiga or Atari, a PC using x86 even then could be using a broad mix of hardware. Developers increasingly used MIDI sequences: instead of writing soundtrack data for each type of soundcard, they generally wrote a fully featured data set for the Roland application that would be compatible with lesser featured equipment so long as it had a MIDI controller to run the sequence. However, different products used different sounds attached to their MIDI controllers. Some tied into the Yamaha FM chip to simulate instruments, some daughterboards of samples had very different sound qualities; meaning that no single sequence performance would be accurate to every other General Midi device.

All of these considerations in the products reflected the high cost of memory storage which rapidly declined with the optical CD format.

Pre-recorded and streaming music[link]

Taking entirely pre-recorded music had many advantages over sequencing for sound quality. Music could be produced freely with any kind and number of instruments, allowing developers to simply record one track to be played back during the game. Quality was only limited by the effort put into mastering the track itself. Memory space costs that was previously a concern was somewhat addressed with optical media becoming the dominant media for software games. CD quality audio allowed for music and voice that had the potential to be truly indistinguishable from any other source or genre of music.

In fourth generation home video games and PCs this was limited to playing a Red Book audio track from a CD while the game was in play (such as Sonic CD). Some of the earliest examples of Red Book audio in video games were later titles of the Ys series, composed by Yuzo Koshiro and Mieko Ishikawa, and arranged by Ryo Yunemitsu for the TurboGrafx-CD from 1989. The Ys soundtracks are still regarded as some of the most influential video game music ever composed.^[18][19][20]

However, there were several disadvantages of regular CD-audio. Optical drive technology was still limited in spindle speed, so playing an audio track from the game CD meant that the system could not access data again until it stopped the track from playing. Looping, the most common form of game music, was also problem as when the laser reached the end of a track, it had to move itself back to the beginning to start reading again causing an audible gap in playback.

To address these drawbacks, some PC game developers designed their own container formats in house, for each application in some cases, to stream compressed audio. This would cut back on memory used for music on the CD, allowed for much lower latency and seek time when finding and starting to play music, and also allowed for much smoother looping due to being able to buffer the data. A minor drawback was that use of compressed audio meant it had to be decompressed which put load on the CPU of a system. As computing power increased, this load became minimal, and in some cases dedicated chips in a computer (such as a sound card) would actually handle all the decompressing.

Fifth generation home console systems also developed specialised streaming formats and containers for compressed audio playback. Sony would call theirs Yellow Book, and offer the standard to other companies. Games would take full advantage of this ability, sometimes with highly praised results (Castlevania: Symphony of the Night). Games ported from arcade machines, which continued to use FM synthesis, often saw superior pre-recorded music streams on their home console counterparts (Street Fighter Alpha 2). Even though the game systems were capable of "CD quality" sound, these compressed audio tracks were not true "CD quality." Many of them had lower sampling rates, but not so significant that most consumers would notice. Using a compressed stream allowed game designers to play back streamed music and still be able to access other data on the disc without interruption of the music, at the cost of CPU power used to render the audio stream. Manipulating the stream any further would require a far more significant level of CPU power available in the 5th generation.

Some games, such as the Wipeout series, continued to use full Red Book CD audio for their soundtracks.

This overall freedom offered to music composers gave video game music the equal footing with other popular music it had lacked. A musician could now, with no need to learn about programming or the game architecture itself, independently produce the music to their satisfaction. This flexibility would be exercised as popular mainstream musicians would be using their talents for video games specifically. An early example is Way of the Warrior on the 3DO, with music by White Zombie. A more well-known example is Trent Reznor's score for Quake.

An alternate approach, as with the TMNT arcade, was to take pre-existing music not written exclusively for the game and use it in the game. The game Star Wars: X-Wing vs. TIE Fighter and subsequent Star Wars games took music composed by John Williams for the Star Wars films of the 1970s and 1980s and used it for the game soundtracks.

Both using new music streams made specifically for the game, and using previously released/recorded music streams are common approaches for developing sound tracks to this day. It is common for X-games sports-based video games to come with some popular artists recent releases (SSX, Tony Hawk, Initial D), as well as any game with heavy cultural demographic theme that has tie-in to music (Need For Speed: Underground, Gran Turismo, and Grand Theft Auto). Sometimes a hybrid of the two are used, such as in Dance Dance Revolution.

Sequencing samples continue to be used in modern gaming for many uses, mostly RPGs. Sometimes a cross between sequencing samples, and streaming music is used. Games such as Republic: The Revolution (music composed by James Hannigan^[21]) and Command & Conquer: Generals (music composed by Bill Brown) have utilised sophisticated systems governing the flow of incidental music by stringing together short phrases based on the action on screen and the player's most recent choices (see dynamic music). Other games dynamically mixed the sound on the game based on cues of the game environment.

As processing power increased dramatically in the 6th generation of home consoles, it became possible to apply special effects in realtime to streamed audio. In SSX, a recent video game series, if a snowboarder takes to the air after jumping from a ramp, the music softens or muffles a bit, and the ambient noise of wind and air blowing becomes louder to emphasize being airborne. When the snowboarder lands, the music resumes regular playback until its next "cue". The LucasArts company pioneered this interactive music technique with their iMUSE system, used in their early adventure games and the Star Wars flight simulators Star Wars: X-Wing and Star Wars: TIE Fighter. Action games such as these will change dynamically to match the amount of danger. Stealth-based games will sometimes rely on such music, either by handling streams differently, or dynamically changing the composition of a sequenced soundtrack.

Personalized soundtracks[link]

Being able to play one's own music during a game in the past usually meant turning down the game audio and using an alternative music player. Some early exceptions were possible on PC/Windows gaming in which it was possible to independently adjust game audio while playing music with a separate program running in the background. Some PC games, such as Quake, play music from the CD while retrieving game data exclusively from the hard disk, thereby allowing the game CD to be swapped for any music CD.

Some PlayStation games supported this by swapping the game CD with a music CD, although when the game needed data, players had to swap the CDs again. One of the earliest games, Ridge Racer, was loaded entirely into RAM, letting the player insert a music CD to provide a soundtrack throughout the entirety of the gameplay. In Vib Ribbon, this became a gameplay feature, with the game generating levels based entirely on the music on whatever CD the player inserted.

Microsoft's Xbox, a competitor in the sixth generation of home consoles opened new possibilities. Its ability to copy music from a CD onto its internal hard drive allowed gamers to use their own music more seamlessly with gameplay than ever before. The feature, called Custom Soundtrack, had to be enabled by the game developer. The feature carried over into the seventh generation with the Xbox 360 except it is now supported by the system software and enabled at any point.

The Wii is also able to play custom soundtracks if it is enabled by the game (Excite Truck,^[22] Endless Ocean^[23]).

The PlayStation Portable can, in games like Need for Speed Carbon: Own the City and FIFA 08, play music from a Memory Stick.

The PlayStation 3 has the ability to utilize custom soundtracks in games using music saved on the hard drive, however few game developers have used this function so far. MLB 08: The Show, released in North America on March 4, 2008, has a My MLB sound track feature which allows the user to play music tracks of their choice saved on the hard drive of their PS3, rather than the preprogrammed tracks incorporated into the game by the developer. An update to Wipeout HD, released on the PlayStation Network, was made to also incorporate this feature.^{[citation needed]}

In Audiosurf, custom soundtracks are the main aspect of the game. Users have to pick a music file to be analyzed. The game will generate a race track based on tempo, pitch and complexity of the sound. The user will then race on this track, synchronized with the music.

The Xbox 360 supports Dolby Digital software, sampling and playback rate of 16-bit @ 48 kHz (internal; with 24-bit hardware D/A converters), hardware codec streaming, and potential of 256 audio simultaneous channels. While powerful and flexible, none of these features represent any major change in how game music is made from the last generation of console systems. PCs continue to rely on third-party devices for in-game sound reproduction, and SoundBlaster, despite being largely the only major player in the entertainment audio expansion card business, continues to advance its product development at a significant pace.^{[citation needed]}

The PlayStation 3 handles multiple types of surround sound technology, including Dolby TrueHD and DTS-HD, with up to 7.1 channels, and with sampling rates of up to 192 kHz.

Nintendo's Wii console shares many audio components with the Nintendo GameCube from the previous generation, including Dolby Pro Logic II. These features are extensions of technology already currently in use.

The game developer of today has many choices on how to develop music. More likely, changes in video game music creation will have very little to do with technology and more to do with other factors of game development as a business whole. As sales of video game music separate from the game itself became marketable in the west (compared to Japan where game music CDs had been selling for years), business elements also wield a level of influence that it had little before. Music from outside the game developer's immediate employment, such as music composers and pop artists, have been contracted to produce game music just as they would for a theatrical movie. Many other factors have growing influence, such as editing for content, politics on some level of the development, executive input and other elements.

Game music as a genre[link]

Many games for the Nintendo Entertainment System and other early game consoles feature a similar style of musical composition that is sometimes described as the "video game genre." Some aspects of this style continue to influence certain music today, though gamers do not associate many modern game soundtracks with the older style. The genre's compositional elements largely developed due to technological restraints, while also being influenced by electronic music bands, particularly Yellow Magic Orchestra (YMO), who were popular during the late 1970s to 1980s.^[24] YMO sampled sounds from several classic arcade games in their early albums, most notably Space Invaders in the 1978 hit song "Computer Game".^[25] In turn, the band would have a major influence on much of the video game music produced during the 8-bit and 16-bit eras.^[24]

Features of the video game music genre include:

• Pieces designed to repeat indefinitely, rather than having an arranged ending or fading out.
• Pieces lacking lyrics and playing over gameplay sounds.
• Limited polyphony. Only three notes can be played simultaneously on the Nintendo Entertainment System. A great deal of effort was put into composition to create the illusion of more notes playing at once.
• Music that changes dynamically while the game is played, for example the volume or tempo.
• Use of Sting (musical phrase)
• Bemani (rhythm games).
• Mock Radio Stations.
• Noise
• Randomly generated music by a computer as in Portal 2.
• Dynamically remixed music during gameplay, including custom soundtracks as in SSX 2012

Although the tones featured in NES music can be thought of emulating a traditional four-piece rock band (triangle wave used as a bass, two pulse waves analogous to two guitars, and a white noise channel used for drums), composers would often go out of their way to compose complex and rapid sequences of notes, in part because of the restrictions mentioned above. This is similar to music composition during the Baroque period, when composers, particularly when creating solo pieces, focused on musical embellishments to compensate for instruments such as the harpsichord that do not allow for expressive dynamics. For the same reason, many early compositions also feature a distinct jazz influence. These would overlap with later influences from heavy metal and j-pop music, resulting in an equally distinct compositional style in the 16-bit era.

In an unrelated but parallel course in the European and North American developer scene, similar limitations were driving the musical style of home computer games. Module file format music, particularly MOD, used similar techniques but was more heavily influenced from the electronic music scene as it developed, and resulted in another very distinct subgenre. Demos and the developing demoscene played a big part in the early years, and still influence video game music today.

As technological limitations gradually lifted, composers were given more freedom and with the advent of CD-ROM pre-recorded soundtracks came to dominate, resulting in a noticeable shift in composition and voicing style.^[26]

As the divisions between movies and video games has blurred, so have divisions between film scores and video game scores. Adventure and fantasy movies have similar needs to adventure and fantasy games, i.e. fanfare, traveling, hero's theme and so on. Some composers have written scores in both genres. One noted example is U.S. composer Michael Giacchino who composed the soundtrack for the game Medal of Honor and later composed for the television series Lost and wrote scores for movies such as The Incredibles (2004) and Star Trek (2009).

Video game music outside video games[link]

Appreciation for video game music, particularly music from the third and fourth generations of home video game console and sometimes newer generations, continues today in very strong representation in both fans and composers alike, even out of the context of a video game. Melodies and themes from 20 years ago continue to be re-used in newer generations of video games. Themes from the original Metroid by Hirokazu Tanaka can still be heard in Metroid games from today as arranged by Kenji Yamamoto.

Video game music soundtracks were sold separately on CD in Japan well before the practice spread to other countries. Interpretive albums, remixes and live performances were also common variations to original soundtracks (OSTs). Koichi Sugiyama was an early figure in this practice sub-genres, and following the release of the first Dragon Quest game in 1986, a live performance CD of his compositions was released and performed by the London Philharmonic Orchestra (then later by other groups including the Tokyo Philharmonic Orchestra, and NHK Symphony). Yuzo Koshiro, another early figure, released a live performance of the Actraiser soundtrack. Both Koshiro's and fellow Falcom composer Mieko Ishikawa's contributions to Ys music would have such long lasting impact that there were more albums released of Ys music than of almost all other game-type music.

Like anime soundtracks, these soundtracks and even sheet music books were usually marketed exclusively in Japan. Therefore, interested non-Japanese gamers have to import the soundtracks and/or sheet music books through on or offline firms specifically dedicated to video game soundtrack imports. This has been somewhat less of an issue more recently as domestic publishers of anime and video games have been producing western equivalent versions of the OSTs for sale in UK and US, but only for the most popular titles in most cases.

Other original composers of the lasting themes from this time have gone on to manage symphonic concert performances to the public exhibiting their work in the games. Koichi Sugiyama was once again the first in this practice in 1987 with his "Family Classic Concert" and has continued concert performances almost annually. In 1991, he also formed a series called Orchestral Game Concerts, notable for featuring other talented game composers such as Yoko Kanno (Nobunaga's Ambition, Romance of the Three Kingdoms, Uncharted Waters), Nobuo Uematsu (Final Fantasy), Keiichi Suzuki (Mother/Earthbound), and Kentaro Haneda (Wizardry).

Following suit, compositions by Nobuo Uematsu on Final Fantasy IV were arranged into Final Fantasy IV: Celtic Moon, a live performance by string musicians with strong celtic influence recorded in Ireland. The Love Theme from the same game has been used as an instructional piece of music in Japanese schools.

Global popularity of video game music would begin to surge with Square's 1990s successes, particularly with Final Fantasy VI, Final Fantasy VII and Final Fantasy VIII by Nobuo Uematsu and with Chrono Trigger, Xenogears and Chrono Cross by Yasunori Mitsuda. On August 20, 2003, for the first time outside Japan, music written for video games such as Final Fantasy and The Legend of Zelda was performed by a live orchestra, the Czech National Symphony Orchestra in a Symphonic Game Music Concert in Leipzig, Germany at the Gewandhaus concert hall. This event was held as the official opening ceremony of Europe's biggest trading fair for video games, the GC Games Convention and repeated in 2004, 2005, 2006 and 2007. On November 17, 2003, Square Enix launched the Final Fantasy Radio on America Online. The radio station has initially featured complete tracks from Final Fantasy XI and Final Fantasy XI: Rise of Zilart and samplings from Final Fantasy VII through Final Fantasy X. The first officially sanctioned Final Fantasy concert in the United States was performed by the Los Angeles Philharmonic Orchestra at Walt Disney Concert Hall in Los Angeles, California, on May 10, 2004. All seats at the concert were sold out in a single day. "Dear Friends: Music from Final Fantasy" followed and was performed at various cities across the United States.

On July 6, 2005, the Los Angeles Philharmonic Orchestra also held a Video Games Live concert, which was founded by video game music composers Tommy Tallarico and Jack Wall at the Hollywood Bowl. This concert featured a variety of video game music, ranging from Pong to Halo 2. It also incorporated real-time video feeds that were in sync with the music, as well as laser and light special effects. Video Games Live has been touring worldwide since. On August 20, 2006, the Malmö Symphonic Orchestra with host Orvar Säfström performed an outdoor concert of game music in Malmö, Sweden before an audience of 17,000, currently the attendance record for a game music concert. From April 20–27, 2007, Eminence Symphony Orchestra, an orchestra dedicated to video game and anime music, performed the first part of their annual tour, the "A Night in Fantasia" concert series in Australia. Whilst Eminence had performed video game music as part of their concerts since their inception, the 2007 concert marked the first time ever that the entire setlist was pieces from video games. Up to seven of the world's most famous game composers were also in attendance as special guests.

On March 16th, 2012 the Smithsonian American Art Museum's "The Art of Video Games" exhibit opened featuring a chipmusic soundtrack at the entrance by artists 8 Bit Weapon & ComputeHer.8 Bit Weapon also created a track called "The art of Video Games Anthem" for the exhibit as well.^[27]

Popular music[link]

In the popular music industry, video game music and sounds have appeared in songs by various popular artists,^[28] with arcade game sounds having had a particularly strong influence on the hip hop,^[29] pop music (particularly synthpop)^[30] and electro music^[31] genres during the golden age of arcade video games in the early 1980s. Arcade game sounds had an influence on synthpop pioneers Yellow Magic Orchestra,^[32] who sampled Space Invaders sounds in their influential 1978 debut album, particularly the hit song "Computer Game".^[25] In turn, the band would have a major influence on much of the video game music produced during the 8-bit and 16-bit eras.^[24]

Other pop songs based on Space Invaders soon followed, including "Disco Space Invaders" (1979) by Funny Stuff,^[33] "Space Invaders" (1980) by Playback,^[34] and the hit songs "Space Invader" (1980) by The Pretenders^[33] and "Space Invaders" (1980) by Uncle Vic.^[35] Buckner & Garcia produced a successful album dedicated to video game music in 1982, Pac-Man Fever.^[36] Former YMO member Haruomi Hosono also released a 1984 album produced entirely from Namco arcade game samples entitled Video Game Music, an early example of a chiptune record^[37] and the first video game music album.^[38] Warp's record "Testone" (1990) by Sweet Exorcist (Richard H. Kirk and Richard Barratt) sampled video game sounds from YMO's "Computer Game" and defined Sheffield's bleep techno scene in the early 1990s.^[39]

In more recent times, "video game beats" have appeared in popular songs such as Kesha's "Tik Tok",^[28] the best-selling single of 2010,^[40] as well as "U Should Know Better" by Robyn featuring Snoop Dogg,^[28] and "Hellbound" by Eminem. The influence of video game music can also be seen in contemporary electronica music by artists such as Dizzee Rascal and Kieran Hebden.^[32] Grime music in particular samples sawtooth wave sounds from video games which were popular in East London.^[41]

Video game music education[link]

Video game music has become part of the curriculum of traditional schools and universities.^[42] Berklee College of Music, Yale University, New York University and the New England Conservatory all feature or are adding game music to their curricula. Game sound & music design has also been part of the curriculum since 2003 at the Utrecht School of the Arts (Faculty of Art, Media and Technology). Training seminars such as GameSoundCon also feature classes in how to compose video game music.^[43]

Extracurricular organizations devoted to the performance of video game music are being established in tandem to these additions to the curriculum. The University of Maryland Gamer Symphony Orchestra performs self-arranged video game music and the Video Game Orchestra is a semiprofessional outgrowth of students from the Berklee College of Music and other Boston-area schools. The establishment of these groups is also occurring at the secondary level.^[44]

Awards[link]

Since 2010, the Ivor Novello Awards has included a category for best original video game score. The 2010 award winner was Killzone 2 (Composed by Joris de Man), and in 2011, Napoleon: Total War (Composers: Richard Beddow, Richard Birdsall, Ian Livingstone)

Spike Video Game Awards includes awards for Best Soundtrack, Best Song in a Game, and Best Original Score.

From 2012, the Grammy Awards will explicitly name "video game music" as part of its "Visual Media (Motion, Television, Video Game Music, or Other Visual Media)" awards. The four Visual Media awards are: Best Music for Visual Media, Best Compilation Soundtrack for Visual Media, Best Score Soundtrack for Visual Media, Best Song Written for Visual Media. In 2011, Baba Yetu, a song from Civilization IV, won the 53rd annual music awards' Best Instrumental Arrangement Accompanying Vocalists, the first video game music to be nominated for (or to win) a Grammy.

The International Film Music Critics Association (IFMCA) has a Best Original Score for Interactive Media award.

Hollywood Music In Media Awards includes a Best Original Video Game Score award.

Machinima.com's Inside Gaming Awards include Best Original Score and Best Sound Design.

The MTV Video Music Award for Best Video Game Soundtrack ran from 2004 to 2006. Additionally an award for Best Video Game Score was awarded only in 2006.

Fan culture[link]

In addition to these professional deviations, a huge network of English speaking fans has sprung up with the help of emulators and the Internet in recent years.^{[citation needed]}

A video game is an electronic game that involves human interaction with a user interface to generate visual feedback on a video device. The word video in video game traditionally referred to a raster display device,^[1] but following popularization of the term "video game", it now implies any type of display device. The electronic systems used to play video games are known as platforms; examples of these are personal computers and video game consoles. These platforms range from large mainframe computers to small handheld devices. Specialized video games such as arcade games, while previously common, have gradually declined in use. Video games have gone on to become an art form and industry.

The input device used to manipulate video games is called a game controller, and varies across platforms. For example, a controller might consist of only a button and a joystick, while another may feature a dozen buttons and one or more joysticks. Early personal computer games often needed a keyboard for gameplay, or more commonly, required the user to buy a separate joystick with at least one button.^[2] Many modern computer games allow or require the player to use a keyboard and a mouse simultaneously. A few of the most common game controllers are gamepads, mice, keyboards, and joysticks.

Video games typically use additional means of providing interactivity and information to the player. Audio is almost universal, using sound reproduction devices, such as speakers and headphones. Other feedback may come via haptic peripherals, such as vibration or force feedback, with vibration sometimes used to simulate force feedback.

In the early days of cartridge consoles, they were sometimes called TV games.

History[link]

Early games used interactive electronic devices with various display formats. The earliest example is from 1947—a "Cathode ray tube Amusement Device" was filed for a patent on January 25, 1947, by Thomas T. Goldsmith Jr. and Estle Ray Mann, and issued on December 14, 1948, as U.S. Patent 2455992.^[3]

Inspired by radar display tech, it consisted of an analog device that allowed a user to control a vector-drawn dot on the screen to simulate a missile being fired at targets, which were drawings fixed to the screen.^[4]

Other early examples include:

• The NIMROD computer at the 1951 Festival of Britain
• OXO a tic-tac-toe Computer game by Alexander S. Douglas for the EDSAC in 1952
• Tennis for Two, an interactive game engineered by William Higinbotham in 1958
• Spacewar!, written by MIT students Martin Graetz, Steve Russell, and Wayne Wiitanen's on a DEC PDP-1 computer in 1961.

Each game used different means of display: NIMROD used a panel of lights to play the game of Nim,^[5] OXO used a graphical display to play tic-tac-toe ^[6] Tennis for Two used an oscilloscope to display a side view of a tennis court,^[4] and Spacewar! used the DEC PDP-1's vector display to have two spaceships battle each other.^[7]

Nolan Bushnell at the Game Developers Conference in 2011

In 1971, Computer Space, created by Nolan Bushnell and Ted Dabney, was the first commercially sold, coin-operated video game. It used a black-and-white television for its display, and the computer system was made of 74 series TTL chips.^[8] The game was featured in the 1973 science fiction film Soylent Green. Computer Space was followed in 1972 by the Magnavox Odyssey, the first home console. Modeled after a late 1960s prototype console developed by Ralph H. Baer called the "Brown Box", it also used a standard television.^[4][9] These were followed by two versions of Atari's Pong; an arcade version in 1972 and a home version in 1975 that dramatically increased video game popularity.^[10] The commercial success of Pong led numerous other companies to develop Pong clones and their own systems, spawning the video game industry.^[11]

A flood of Pong clones eventually led to the video game crash of 1977, which came to an end with the mainstream success of Taito's 1978 shooter game Space Invaders,^[12] marking the beginning of the golden age of arcade video games and inspiring dozens of manufacturers to enter the market.^[12][13] The game inspired arcade machines to become prevalent in mainstream locations such as shopping malls, traditional storefronts, restaurants, and convenience stores.^[14] The game also became the subject of numerous articles and stories on television and in newspapers and magazines, establishing video gaming as a rapidly growing mainstream hobby.^[15][16] Space Invaders was soon licensed for the Atari VCS (later known as Atari 2600), becoming the first "killer app" and quadrupling the console's sales.^[17] This helped Atari recover from their earlier losses,^[18] and in turn the Atari VCS revived the home video game market during the second generation of consoles, up until the North American video game crash of 1983.^[19] The home video game industry was revitalized shortly afterwards by the widespread success of the Nintendo Entertainment System,^[20] which marked a shift in the dominance of the video game industry from the United States to Japan during the third generation of consoles.^[21]

Overview[link]

Platforms[link]

The term "platform" refers to the specific combination of electronic components or computer hardware which, in conjunction with software, allows a video game to operate.^[22] The term "system" is also commonly used.

In common use a "PC game" refers to a form of media that involves a player interacting with a IBM PC compatible personal computer connected to a video monitor. A "console game" is played on a specialized electronic device that connects to a common television set or composite video monitor. A "handheld" gaming device is a self contained electronic device that is portable and can be held in a user's hands. "Arcade game" generally refers to a game played on an even more specialized type of electronic device that is typically designed to play only one game and is encased in a special cabinet. These distinctions are not always clear and there may be games that bridge one or more platforms. In addition to personal computers, there are multiple other devices which have the ability to play games but are not dedicated video game machines, such as mobile phones, PDAs and graphing calculators.

With the advent of social networking and other online applications hubs, the term "platform" started being used to refer to the online service within which the game is played, regardless of the actual hardware on which it is executed. A game's platform could simply be "Facebook", whether it is played on a Windows PC, Mac, Smart TV, or smartphone.

Genres[link]

A video game, like most other forms of media, may be categorized into genres based on many factors such as method of game play, types of goals, art style and more. Because genres are dependent on content for definition, genres have changed and evolved as newer styles of video games have come into existence. Ever advancing technology and production values related to video game development have fostered more life-like and complex games which have in turn introduced or enhanced genre possibilities (e.g., virtual pets), pushed the boundaries of existing video gaming or in some cases add new possibilities in play (such as that seen with titles specifically designed for devices like Sony's EyeToy). Some genres represent combinations of others, such as massively multiplayer online role-playing games, or, more commonly, MMORPGs. It is also common to see higher level genre terms that are collective in nature across all other genres such as with action, music/rhythm or horror-themed video games.

Classifications[link]

Casual games[link]

Casual games derive their name from their ease of accessibility, simple to understand gameplay and quick to grasp rule sets. Additionally, casual games frequently support the ability to jump in and out of play on demand. Casual games as a format existed long before the term was coined and include video games such as Solitaire or Minesweeper which can commonly be found pre-installed with many versions of the Microsoft Windows operating system.

Examples of genres within this category are hidden object, match three, time management, tetris or many of the tower defense style games. Casual games are generally sold through online retailers such as PopCap, Zylom, Vans Video Games and GameHouse or provided for free play through web portals such as Newgrounds or AddictingGames.

While casual games are most commonly played on personal computers, cellphones or PDAs, they can also be found on many of the on-line console system download services (e.g., Xbox Live, PlayStation Network, or WiiWare).

Serious games[link]

Serious games are games that are designed primarily to convey information or a learning experience of some sort to the player. Some serious games may even fail to qualify as a video game in the traditional sense of the term. Educational software does not typically fall under this category (e.g., touch typing tutors, language learning, etc.) and the primary distinction would appear to be based on the title's primary goal as well as target age demographics. As with the other categories, this description is more of a guideline than a rule.

Serious games are games generally made for reasons beyond simple entertainment and as with the core and casual games may include works from any given genre, although some such as exergames, educational games, or propaganda games may have a higher representation in this group due to their subject matter. These games are typically designed to be played by professionals as part of a specific job or for skill set improvement. They can also be created to convey social-political awareness on a specific subject.

One of the longest running serious games franchises would be Microsoft Flight Simulator first published in 1982 under that name. The United States military uses virtual reality based simulations, such as VBS1 for training exercises,^[23] as do a growing number of first responder roles (e.g., police, fire fighter, EMT).^[24] One example of a non-game environment utilized as a platform for serious game development would be the virtual world of Second Life, which is currently used by several United States governmental departments (e.g., NOAA, NASA, JPL), Universities (e.g., Ohio University, MIT) for educational and remote learning programs^[25] and businesses (e.g., IBM, Cisco Systems) for meetings and training.^[26]

Tactical media in video games plays a crucial role in making a statement or conveying a message on important relevant issues. This form of media allows for a broader audience to be able to receive and gain access to certain information that otherwise may not have reached such people. An example of tactical media in video games would be newsgames. These are short games related to contemporary events designed to illustrate a point.^[27] For example, Take Action Games is a game studio collective that was co-founded by Susana Ruiz and has made successful serious games. Some of these games include Darfur is Dying, Finding Zoe, and In The Balance. All of these games bring awareness to important issues and events in an intelligent and well thought out manner.^[28]

Educational games[link]

On September 23, 2009, U.S. President Barack Obama launched a campaign called "Educate to Innovate" aimed at improving the technological, mathematical, scientific and engineering abilities of American students. This campaign states that it plans to harness the power of interactive games to help achieve the goal of students excelling in these departments.^[29][30] This campaign has stemmed into many new and exciting opportunities for the video game realm and has contributed to many new competitions. Some of these competitions include the Stem National Video Game Competition and the Imagine Cup.^[31][32] Both of these examples are events that bring a focus to relevant and important current issues that are able to be addressed in the sense of video games to educate and spread knowledge in a new form of media. www.NobelPrize.org uses games to entice the user to learn about information pertaining to the Nobel prize achievements while engaging in a fun to play video game.^[33] There are many different types and styles of educational games all the way from counting to spelling to games for kids and games for adults. Some other games do not have any particular targeted audience in mind and intended to simply educate or inform whoever views or plays the game.

Development[link]

Developers use various tools to create video games, here an editor to fine tune the virtual camera system.

Video game development and authorship, much like any other form of entertainment, is frequently a cross-disciplinary field. Video game developers, as employees within this industry are commonly referred, primarily include programmers and graphic designers. Over the years this has expanded to include almost every type of skill that one might see prevalent in the creation of any movie or television program, including sound designers, musicians, and other technicians; as well as skills that are specific to video games, such as the game designer. All of these are managed by producers.

In the early days of the industry, it was more common for a single person to manage all of the roles needed to create a video game. As platforms have become more complex and powerful in the type of material they can present, larger teams have been needed to generate all of the art, programming, cinematography, and more. This is not to say that the age of the "one-man shop" is gone, as this is still sometimes found in the casual gaming and handheld markets,^[34] where smaller games are prevalent due to technical limitations such as limited RAM or lack of dedicated 3D graphics rendering capabilities on the target platform (e.g., some cellphones and PDAs).^{[citation needed]}

With the growth of the size of development teams in the industry, the problem of cost has increased. Development studios need to be able to pay their staff a competitive wage in order to attract and retain the best talent, while publishers are constantly looking to keep costs down in order to maintain profitability on their investment. Typically, a video game console development team can range in sizes of anywhere from 5 to 50 people, with some teams exceeding 100. In May 2009, one game project was reported to have a development staff of 450.^[35] The growth of team size combined with greater pressure to get completed projects into the market to begin recouping production costs has led to a greater occurrence of missed deadlines and unfinished products.^{[citation needed]}

Downloadable content[link]

A newer phenomenon of withholding content from the game and then releasing it at a later date for additional funds not factored into the retail price began with digital video game distribution known as Downloadable Content (also known colloquially as 'DLC'). Studios may choose to utilize this to issue original content after the game is released, such as Rockstar Games with Grand Theft Auto IV, or Bethesda with Fallout 3, yet often opt instead to create content before the game is released to be intentionally withheld, such as Activision and Treyarch with Call of Duty (Despite knowing well public affection for a 'Zombies' game mode, it was shipped with only one map for this game mode, and periodically releases new ones with $10 DLC).^[36][37][38]

Modifications[link]

Many games produced for the PC are designed such that technically oriented consumers can modify the game. These mods can add an extra dimension of replayability and interest. Developers such as id Software, Valve Software, Crytek, Bethesda, Epic Games and Blizzard Entertainment ship their games with some of the development tools used to make the game, along with documentation to assist mod developers. The Internet provides an inexpensive medium to promote and distribute mods, and they may be a factor in the commercial success of some games.^[39] This allows for the kind of success seen by popular mods such as the Half-Life mod Counter-Strike.

Cheating[link]

Cheating in computer games may involve cheat codes and hidden spots implemented by the game developers,^[40][41] modification of game code by third parties,^[42][43] or players exploiting a software glitch. Modifications are facilitated by either cheat cartridge hardware or a software trainer.^[42] Cheats usually make the game easier by providing an unlimited amount of some resource; for example weapons, health, or ammunition; or perhaps the ability to walk through walls.^[41][42] Other cheats might give access to otherwise unplayable levels or provide unusual or amusing features, like altered game colors or other graphical appearances.

Glitches[link]

Software errors not detected by software testers during development can find their way into released versions of computer and video games. This may happen because the glitch only occurs under unusual circumstances in the game, was deemed too minor to correct, or because the game development was hurried to meet a publication deadline. Glitches can range from minor graphical errors to serious bugs that can delete saved data or cause the game to malfunction. In some cases publishers will release updates (referred to as patches) to repair glitches. Sometimes a glitch may be beneficial to the player, these are often referred to as exploits.

Easter eggs[link]

Easter eggs are hidden messages or jokes left in games by developers that are not part of the main game.

Theory[link]

Although departments of computer science have been studying the technical aspects of video games for years, theories that examine games as an artistic medium are a relatively recent development in the humanities. The two most visible schools in this emerging field are ludology and narratology. Narrativists approach video games in the context of what Janet Murray calls "Cyberdrama". That is to say, their major concern is with video games as a storytelling medium, one that arises out of interactive fiction. Murray puts video games in the context of the Holodeck, a fictional piece of technology from Star Trek, arguing for the video game as a medium in which we get to become another person, and to act out in another world.^[44] This image of video games received early widespread popular support, and forms the basis of films such as Tron, eXistenZ and The Last Starfighter.

Ludologists break sharply and radically from this idea. They argue that a video game is first and foremost a game, which must be understood in terms of its rules, interface, and the concept of play that it deploys. Espen J. Aarseth argues that, although games certainly have plots, characters, and aspects of traditional narratives, these aspects are incidental to gameplay. For example, Aarseth is critical of the widespread attention that narrativists have given to the heroine of the game Tomb Raider, saying that "the dimensions of Lara Croft's body, already analyzed to death by film theorists, are irrelevant to me as a player, because a different-looking body would not make me play differently... When I play, I don't even see her body, but see through it and past it."^[45] Simply put, ludologists reject traditional theories of art because they claim that the artistic and socially relevant qualities of a video game are primarily determined by the underlying set of rules, demands, and expectations imposed on the player.

While many games rely on emergent principles, video games commonly present simulated story worlds where emergent behavior occurs within the context of the game. The term "emergent narrative" has been used to describe how, in a simulated environment, storyline can be created simply by "what happens to the player."^[46] However, emergent behavior is not limited to sophisticated games. In general, any place where event-driven instructions occur for AI in a game, emergent behavior will exist. For instance, take a racing game in which cars are programmed to avoid crashing, and they encounter an obstacle in the track: the cars might then maneuver to avoid the obstacle causing the cars behind them to slow and/or maneuver to accommodate the cars in front of them and the obstacle. The programmer never wrote code to specifically create a traffic jam, yet one now exists in the game.

Social aspects[link]

Demographics[link]

The November 2005 Nielsen Active Gamer Study, taking a survey of 2,000 regular gamers, found that the U.S. games market is diversifying. The age group among male players has expanded significantly in the 25–40 age group. For casual online puzzle-style and simple mobile cell phone games, the gender divide is more or less equal between males and females. Females have also been found to show an attraction to online multi-player games where there is a communal experience.^{[citation needed]} More recently there has been a growing segment of female players engaged with the aggressive style of games historically considered to fall within traditionally male genres (e.g., first-person shooters). According to the ESRB almost 41% of PC gamers are women^[47] (see Girl gamer).

When comparing today's industry climate with that of 20 years ago, women and many adults are more inclined to be using products in the industry. While the market for teen and young adult men is still a strong market, it is the other demographics which are posting significant growth. The Entertainment Software Association (ESA) provides the following summary for 2011 based on a study of almost 1,200 American households carried out by Ipsos MediaCT:^[48]

• The average gamer is 37 years old and has been playing for 12 years. Eighty-two percent of gamers are 18 years of age or older.
• Forty-two percent of all players are women and women over 18 years of age are one of the industry's fastest growing demographics.
• Today, adult women represent a greater portion of the game-playing population (37 percent) than boys age 17 or younger (13 percent).
• Twenty-nine percent of game players are over the age of 50, an increase from nine percent in 1999.
• Sixty-five percent of gamers play games with other gamers in person.
• Fifty-five percent of gamers play games on their phones or handheld device.

A 2006 academic study, based on a survey answered by 10.000 gamers, identified the gaymers (gamers that identify as LGBT) as a significant demographic group. ^{[49] [50][51]} A followup survey in 2009 studied the purchase habits and content preferences of people in the group.^[52][53][54]

Based on the study by NPD group in 2011, about 91 percent of kids aged 2–17 play games.^[55]

Multiplayer[link]

Video gaming has traditionally been a social experience. Multiplayer video games are those that can be played either competitively, sometimes in Electronic Sports, or cooperatively by using either multiple input devices, or by hotseating. Tennis for Two, arguably the first video game, was a two player game, as was its successor Pong. The first commercially available game console, the Magnavox Odyssey, had two controller inputs.

Since then, most consoles have been shipped with two or four controller inputs. Some have had the ability to expand to four, eight or as many as 12 inputs with additional adapters, such as the Multitap. Multiplayer arcade games typically feature play for two to four players, sometimes tilting the monitor on its back for a top-down viewing experience allowing players to sit opposite one another.

Many early computer games for non-PC descendant based platforms featured multiplayer support. Personal computer systems from Atari and Commodore both regularly featured at least two game ports. PC-based computer games started with a lower availability of multiplayer options because of technical limitations. PCs typically had either one or no game ports at all. Network games for these early personal computers were generally limited to only text based adventures or MUDs that were played remotely on a dedicated server. This was due both to the slow speed of modems (300-1200-bit/s), and the prohibitive cost involved with putting a computer online in such a way where multiple visitors could make use of it. However, with the advent of widespread local area networking technologies and Internet based online capabilities, the number of players in modern games can be 32 or higher, sometimes featuring integrated text and/or voice chat. MMOs can offer extremely high numbers of simultaneous players; Eve Online set a record with 54,446 players on a single server in 2010.^[56]

Benefits[link]

It has been shown that action video game players have better hand-eye coordination and visuo-motor skills, such as their resistance to distraction, their sensitivity to information in the peripheral vision and their ability to count briefly presented objects, than nonplayers.^[57]

Researchers found that such enhanced abilities could be acquired by training with action games, involving challenges that switch attention between different locations, but not with games requiring concentration on single objects. It has been suggested by a few studies that online/offline video gaming can be used as a therapeutic tool in the treatment of different mental health concerns.^[which?]

In Steven Johnson's book, Everything Bad Is Good for You, he argues that video games in fact demand far more from a player than traditional games like Monopoly. To experience the game, the player must first determine the objectives, as well as how to complete them. They must then learn the game controls and how the human-machine interface works, including menus and HUDs. Beyond such skills, which after some time become quite fundamental and are taken for granted by many gamers, video games are based upon the player navigating (and eventually mastering) a highly complex system with many variables. This requires a strong analytical ability, as well as flexibility and adaptability. He argues that the process of learning the boundaries, goals, and controls of a given game is often a highly demanding one that calls on many different areas of cognitive function. Indeed, most games require a great deal of patience and focus from the player, and, contrary to the popular perception that games provide instant gratification, games actually delay gratification far longer than other forms of entertainment such as film or even many books.^[58] Some research suggests video games may even increase players' attention capacities.^[59]

Learning principles found in video games have been identified as possible techniques with which to reform the U.S. education system.^[60] It has been noticed that gamers adopt an attitude while playing that is of such high concentration, they do not realize they are learning, and that if the same attitude could be adopted at school, education would enjoy significant benefits.^[61] Students are found to be "learning by doing" while playing video games while fostering creative thinking.^[62]

The U.S. Army has deployed machines such as the PackBot and UAV vehicles, which make use of a game-style hand controller to make it more familiar for young people.^[63]

According to research discussed at the 2008 Convention of the American Psychological Association, certain types of video games can improve the gamers' dexterity as well as their ability to problem-solve. A study of 33 laparoscopic surgeons found that those who played video games were 27 percent faster at advanced surgical procedures and made 37 percent fewer errors compared to those who did not play video games. A second study of 303 laparoscopic surgeons (82 percent men; 18 percent women) also showed that surgeons who played video games requiring spatial skills and hand dexterity and then performed a drill testing these skills were significantly faster at their first attempt and across all 10 trials than the surgeons who did not play the video games first.^[64]

Whilst many studies have detected superior mental aptitudes^[which?] amongst habitual gamers, research by Walter Boot at the University of Illinois found that non-gamers showed no improvement in memory or multitasking abilities after 20 hours of playing three different games. The researchers suggested that "individuals with superior abilities are more likely to choose video gaming as an activity in the first place".^[65]Unreliable - Discuss

Controversy[link]

Like related forms of media, computer and video games have been the subject of frequent controversy and censorship, due to the depiction of graphic violence, sexual themes, advergaming (a form of advertising in games), consumption of drugs, consumption of alcohol or tobacco, propaganda, or profanity in some games. Among others, critics of video games often include parents' groups, politicians, organized religious groups, and other advocacy groups. Various games have been accused of causing addiction and even violent behavior,^[66][67] though how much ground this holds is debatable.^[68][69] "Video game censorship" is defined as the use of state or group power to control the playing, distribution, purchase, or sale of video games or computer games. Video game controversy comes in many forms, and censorship is a controversial subject. Proponents and opponents of censorship are often very passionate about their individual views.

Various national content rating organizations, such as the Entertainment Software Ratings Board or ESRB in North America, rate software for certain age groups and with certain content warnings. Some of these organizations are optional industry self-regulation (such as the ESRB), while others are part of national government censorship organizations. Most video games display their rating on the front side of their packaging. However, parents are not always aware of the existence of these ratings. Not all ratings are considered accurate. Organizations such as What They Play and Common Sense Media aim to provide guidance and advice for parents.^[70]

Ratings and censorship[link]

ESRB[link]

The Entertainment Software Rating Board (ESRB) gives videogames maturity ratings based on their content. For example, a game might be rated T for Teen if the game contained obscene words or violence. If a game contains explicit violence or sexual themes, it is likely to receive an M for Mature rating, which means that no one under 17 should play it. There is a rated "A/O" games for "Adults Only" these games have massive violence or nudity. There are no laws that prohibit children from purchasing "M" rated games in the United States. Laws attempting to prohibit minors from purchasing "M" rated games were established in California, Illinois, Michigan, Minnesota, and Louisiana, but all were overturned on the grounds that the establishment of such laws were in violation of a child's First Amendment rights^{[citation needed]}. However, many stores have opted to not sell such games to children anyway. Of course, video game laws vary from country to country. One of the most controversial games of all time, Manhunt 2 by Rockstar Studios, was denied a rating by the ESRB until Rockstar could make the content more suitable for a mature audience.

Video game manufacturers usually exercise tight control over the games that are made available on their systems, so unusual or special-interest games are more likely to appear as PC games. Free, casual, and browser-based games are usually played on available computers, mobile phones, or PDAs.

PEGI[link]

Pan European Game Information (PEGI) is a system that was developed to standardize the game ratings in all of Europe (not just European Union, although the majority are EU members), the current members are: all EU members, except Germany and the 10 accession states; Norway; Switzerland. Iceland is expected to join soon, as are the 10 EU accession states. For all PEGI members, they use it as their sole system, with the exception of the UK, where if a game contains certain material,^[71] it must be rated by BBFC. The PEGI ratings are legally binding in Vienna and it is a criminal offence to sell a game to someone if it is rated above their age.^[72]

Germany: BPjM and USK[link]

Stricter game rating laws mean that Germany does not operate within the PEGI. Instead, they adopt their own system of certification which is required by law. The Unterhaltungssoftware Selbstkontrolle (USK or Voluntary Certification of Entertainment Software) checks every game before release and assigns an age rating to it - either none (white), 6 years of age (yellow), 12 years of age (green), 16 years of age (blue) or 18 years of age (red). It is forbidden for anyone, retailers, friends or parents alike, to allow a child access to a game for which he or she is underage. If a game is particularly violent, it may be referred to the BPjM (Bundesprüfstelle für jugendgefährdende Medien - Federal Verification Office for Child-Endangering Media) who may opt to place it on the Index upon which the game may not be sold openly or advertised in the open media. Unofficially, the titles are not "banned" - adult gamers are still technically free to obtain the titles by other means, although it is still considered a felony to supply these titles to a child.

Commercial aspects[link]

Game sales[link]

A typical retail display (in Geneva, Switzerland) with a large selection of games for several major consoles

The three largest producers of and markets for computer and video games (in order) are North America (US and Canada), Japan and the United Kingdom. Other significant markets include Australia, Spain, Germany, South Korea, Mexico, France and Italy.^[73] Both India and China are considered emerging markets in the video game industry and sales are expected to rise significantly in the coming years. Irish are the largest per capita consumers of video games.^[74]

Sales of different types of games vary widely between these markets due to local preferences. Japanese consumers tend to purchase much more console games than computer games, with a strong preference for games catering to local tastes. Another key difference is that, despite the decline of arcades in the Western world (see Golden age of video arcade games), arcade games remain the largest sector of the Japanese gaming industry. As of 2009, the Japanese gaming industry is worth $20 billion, including $6 billion from arcades, $3.5 billion from console game sales, and $2 billion from mobile game sales.^[75] In South Korea, computer games are generally preferred over console games, especially MMORPG games and real-time strategy games. There are over 20,000 Internet cafés in South Korea where computer games can be played for an hourly charge. Computer games are also popular in China, which has a PC gaming industry worth $6 billion, the largest in the world.^[76] Arcade games are also still a thriving industry in China, though console games have been banned in the country since the early 2000s.^[77]

The NPD Group tracks computer and video game sales in the United States. It reported in 2004 that:

• Console and portable software sales: $6.2 billion, up 8% from 2003^[78]
• Console and portable hardware and accessory sales: $3.7 billion, down 35% from 2003^[78]
• PC game sales: $1.1 billion, down 15% from 2006^[79]

PC games that are digitally distributed either directly or by networks such as Steam are not tracked by the NPD, and Valve does not list sales numbers for games downloaded through their service. Unauthorized distribution is also rampant on the PC.^[80]

These figures are sales in dollars, not units, Unit shipments for each category were higher than the dollar sales numbers indicate, because more software and hardware was discounted than in 2003. But with the release of the next-generation consoles in 2006, these numbers increased dramatically. The game and film industries are also becoming increasingly intertwined, with companies like Sony having significant stakes in both. A large number of summer blockbuster films spawn a companion game, often launching at the same time to share the marketing costs.

The global market for console games has seen an average of 6.9 percent compound annual growth rate and is expected to become a $34.7 billion market in 2012.Online game sales are expected to grow at a larger rate of 16.9 percent, escalating from $6.6 billion in 2008 to $14.4 billion by 2012. The largest channel for growth, however, is in mobile gaming with a growth rate of 19 percent; estimated to grow from $5.6 billion in 2008 to $13.5 billion in four years.^[81]

Criticism[link]

Video games have the problem of regional lockout. In Australia, while most DVD players are sold region-free to accommodate local consumer rights legislation,^[82] video game consoles are still sold fully region protected. Some effort has been made to increase awareness of the issue, specifically to Nintendo of Australia,^[83] in the form of a formal report outlining the issues, published by Aaron Rex Davies.^[84] The report has gone on to gain a lot of attention in the public media.^[85]

Museums[link]

There are many video game museums around the world, for example Museum of Soviet Arcade Machines in Moscow^[86] or Computer Game Museum in Berlin.^[87]

The Smithsonian American Art Museum is running an exhibition on "The Art of Video Games".^[88]
