Defense of the Ancients

Defense of the Ancients (DotA) is a multiplayer online battle arena mod for the video game Warcraft III: Reign of Chaos and its expansion, Warcraft III: The Frozen Throne, based on the "Aeon of Strife" map for StarCraft. The scenario objective is for each team to destroy the opponents' Ancient, heavily guarded structures at opposing corners of the map. Players use powerful units known as heroes, and are assisted by allied heroes and AI-controlled fighters. As in role-playing games, players level up their heroes and use gold to buy equipment during the mission.

The scenario was developed with the "World Editor" of Reign of Chaos, and was updated upon the release of its expansion, The Frozen Throne. There have been many variations of the original concept; the most popular being DotA Allstars, which eventually was simplified to DotA with the release of version 6.68. This specific scenario has been maintained by several authors during development, the latest of whom is the anonymous developer known as "IceFrog" who has developed the game since 2005.

Dota 2

Dota 2 is a free-to-play multiplayer online battle arena (MOBA) video game developed and published by Valve Corporation. The game was released for Microsoft Windows, OS X, and Linux in July 2013, following a Windows-only public beta testing phase that began in 2011, and is the stand-alone sequel to Defense of the Ancients (DotA), a mod for Warcraft III: Reign of Chaos and its expansion pack, The Frozen Throne. Dota 2 is one of the most actively played games on Steam, with maximum peaks of over a million concurrent players.

Dota 2 is played in matches between two five-player teams, each of which occupies a stronghold in a corner of the playing field. A team wins by destroying the other side's "Ancient" building, located within the opposing stronghold. Each player controls one of 111 playable "Hero" characters that feature unique powers and styles of play. During a match, the player collects gold, items, and experience points for their Hero, while combating Heroes of the opposite team.

ARMA 2

ARMA 2 is a military simulation video game for Microsoft Windows, developed by Bohemia Interactive. It is the sequel to ARMA: Armed Assault (ARMA: Combat Operations in North America), and preceding ARMA 3. ARMA 2 saw a limited release in May 2009, and a wide release from June 2009 through July 2009. An expansion pack titled ARMA 2: Operation Arrowhead was released in 2010. In June 2011, a free version of the game was released, featuring multiplayer and limited single player modes. It is also considered the official successor of Operation Flashpoint: Cold War Crisis (under the title ARMA: Cold War Assault by Bohemia Interactive).

The game had sold 2.3 million copies as of February 2015.

Gameplay

ARMA 2 is a tactical shooter focused primarily on infantry combat, but significant vehicular and aerial combat elements are present. The player is able to command AI squad members which adds a real-time strategy element to the game. This is further enhanced by the high command system, which allows the player to command multiple squads using the map. ARMA 2 is set primarily in the fictional Eastern European nation of Chernarus (meaning "Black Rus"). The Chernarussian landscape is based heavily on the Czech Republic; the home country of the developer.

Greatest hits album

A greatest hits album, sometimes called a "best of" album or a catalog album, is a compilation of songs by a particular artist or band. Most often the track list contains previously released recordings with a high degree of notability. However, to increase the appeal, especially to people who already own the original release, it is common to include remixes and/or alternate takes of popular songs; even new material (previously unreleased). At times a greatest hits compilation is the original release for songs that have themselves been released as a single and charted successfully.

Notable compilations

Madonna's The Immaculate Collection is the best selling greatest hits compilation by a solo artist; all of the songs on it are presented in different versions than the original hit versions. The Eagles' Their Greatest Hits (1971–1975) is the best selling greatest hits compilation by a group and also one of the ten best selling albums in history. Greatest hits albums are typically produced after an artist has had enough successful songs to fill out an album release. Some artists, such as Mariah Carey, Madonna, Janet Jackson, Britney Spears, Elvis Presley, Michael Jackson, The Beatles, Kenny Rogers, Aerosmith, Kiss, U2, Dolly Parton, Journey, Los Tigres del Norte, Queen, Kylie Minogue and Billy Joel, have released multiple greatest hits albums through their long careers. Some greatest hits albums are released only at the end of the artist or group's career. For example, My Chemical Romance released a greatest hits album after they disbanded. Other artists, like Eminem have released hits albums in the center of their success. He released Curtain Call: The Hits in 2005 and then Shady XV as a compilation album in 2014.

The organization has released several copyright-licenses known as Creative Commons licenses free of charge to the public. These licenses allow creators to communicate which rights they reserve, and which rights they waive for the benefit of recipients or other creators. An easy-to-understand one-page explanation of rights, with associated visual symbols, explains the specifics of each Creative Commons license. Creative Commons licenses do not replace copyright, but are based upon it. They replace individual negotiations for specific rights between copyright owner (licensor) and licensee, which are necessary under an "all rights reserved" copyright management, with a "some rights reserved" management employing standardized licenses for re-use cases where no commercial compensation is sought by the copyright owner. The result is an agile, low-overhead and low-cost copyright-management regime, profiting both copyright owners and licensees. Wikipedia uses one of these licenses.
