Russia (ⁱ/ˈrʌʃə/; Russian: Росси́я, tr. Rossiya; IPA: [rɐˈsʲijə]), also officially known as the Russian Federation (Russian: Росси́йская Федера́ция, tr. Rossiyskaya Federatsiya; IPA: [rɐˈsʲijskəjə fʲɪdʲɪˈratsɨjə]), is a sovereign state in northern Eurasia. It is a federal semi-presidential republic. At 17,125,200 square kilometres (6,612,100 sq mi), Russia is the largest country in the world, covering more than one-eighth of the Earth's inhabited land area. Russia is the world's ninth most populous country with over 144 million people at the end of 2015.

Extending across the entirety of northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a wide range of environments and landforms. From northwest to southeast, Russia shares land borders with Norway, Finland, Estonia, Latvia, Lithuania and Poland (both with Kaliningrad Oblast), Belarus, Ukraine, Georgia, Azerbaijan, Kazakhstan, China, Mongolia, and North Korea. It shares maritime borders with Japan by the Sea of Okhotsk and the U.S. state of Alaska across the Bering Strait.

North Korea ( listen), officially the Democratic People's Republic of Korea (DPRK; Chosŏn'gŭl: 조선민주주의인민공화국; hancha: 朝鮮民主主義人民共和國; MR: Chosŏn Minjujuŭi Inmin Konghwaguk), is a country in East Asia, in the northern part of the Korean Peninsula. The name Korea is derived from the Kingdom of Goguryeo, also spelled as Koryŏ. The capital and largest city is Pyongyang. North Korea shares a land border with China to the north and northwest, along the Amnok (Yalu) and Tumen rivers, and a small section of the Tumen River also forms a border with Russia to the northeast. The Korean Demilitarized Zone marks the boundary between North Korea and South Korea.

Korea was annexed by the Empire of Japan in 1910. After the Japanese surrender at the end of World War II in 1945, Korea was divided into two zones by the United States and the Soviet Union, with the north occupied by the Soviets and the south by the Americans. Negotiations on reunification failed, and in 1948 two separate governments were formed: the Democratic People's Republic of Korea in the north, and the Republic of Korea in the south. An invasion initiated by North Korea led to the Korean War (1950–53). Although the Korean Armistice Agreement brought about a ceasefire, no official peace treaty was ever signed. Both states were accepted into the United Nations in 1991.

World War III

World War III (WWIII, WW3 or the Third World War) is a hypothetical worldwide military conflict subsequent to World War II. Because of the development and use of nuclear weapons near the end of World War II and their subsequent acquisition and deployment by several countries, it is feared that a third world war could cause the end of human civilization and most or all human life on Earth. A common hypothesis is that a small number of people could survive such an Armageddon, possibly in deep underground blast shelters or away from Earth, such as on the Moon or Mars or in space vehicles. Another major concern is that biological warfare could cause a very large number of casualties, either intentionally or inadvertently by an accidental release of a biological agent, the unexpected mutation of an agent, or its adaptation to other species after use.

One of the first imagined scenarios, hypothesized shortly after or even during World War II, was a nuclear war between the United States and the Soviet Union, which emerged as superpowers following World War II. This has been widely used as a premise or plot device in books, films, television productions, and video games. A few writers have instead applied the term "World War III" to the Cold War, arguing that it met the definition of a world war even though there was no direct armed conflict between the superpowers.

Artillery game

Artillery games are early two or three-player (usually turn-based) video games involving tanks fighting each other in combat or similar. Artillery games are among the earliest computer games developed; the theme of such games is an extension of the original uses of computer themselves, which were once used to calculate the trajectories of rockets and other related military-based calculations. Artillery games have been described as a type of "shooting game", though they are more often classified as a type of strategy video game.

Early precursors to the modern artillery-type games were text-only games that simulated artillery entirely with input data values. A BASIC game known simply as Artillery was written by Mike Forman and was published in Creative Computing magazine in 1976. This seminal home computer version of the game was revised in 1977 by M. E. Lyon and Brian West and was known as War 3; War 3 was revised further in 1979 and published as Artillery-3. These early versions of turn-based tank combat games interpreted human-entered data such as the distance between the tanks, the velocity or "power" of the shot fired and the angle of the tanks' turrets.

South Korea ( listen), officially the Republic of Korea (Hangul: 대한민국; hanja: 大韓民國; RR: Daehanminguk,  listen) and commonly referred to as Korea, is a sovereign state in East Asia, constituting the southern part of the Korean Peninsula. The name Korea is derived from the ancient Kingdom of Goguryeo, also known as Koryŏ. Highly urbanized at 92%, Koreans lead a distinctive urban lifestyle with half of them living in the Seoul Capital Area, the world's second largest city with over 25 million residents and a leading global city with the fourth largest economy, rated in 2016 as the world's most livable megacity and safest city to live in. Highly mountainous, Korea is a popular winter sport destination in Asia, hosting the 2018 Winter Olympics.

The earliest Korean pottery dates to 8000 BC, with three kingdoms flourishing at 1st century BC. One of them, Goguryeo, ruled Northeast China, parts of Russia and Mongolia under Gwanggaeto the Great. Since their unification into Silla and Balhae in the 7th century, Korea enjoyed over a millennium of relative tranquility under long lasting dynasties with innovations like Hangul, the unique alphabet created by Sejong the Great in 1446, enabling anyone to easily learn to read and write. Its rich and vibrant culture left 17 UNESCO Intangible Cultural Heritages of Humanity, the third largest in the world, along with 12 World Heritage Sites. Korea was annexed by Imperial Japan in 1910 due to its strategic and central location, after whose surrender in 1945, it was divided into North and South Korea. A North Korean invasion lead to the Korean War (1950–53). Peace has since mostly continued with the two agreeing to work peacefully for reunification and the South solidifying peace as a regional power with the world's 10th largest defence budget and strong global alliances. In 2016, Korea was rated as the world's safest country to live in, with the lowest crime rate.
