Civilization

Sid Meier's Civilization is a 1991 turn-based strategy 4X video game developed and published by MicroProse. The game was originally developed for MS-DOS running on a PC, and it has undergone numerous revisions for various platforms. The player is tasked with leading an entire human civilization over the course of several millennia by controlling various areas such as urban development, exploration, government, trade, research, and military. The player can control individual units and advance the exploration, conquest and settlement of the game's world. The player can also make such decisions as setting forms of government, tax rates and research priorities. The player's civilization is in competition with other computer-controlled civilizations, with which the player can enter diplomatic relationships that can either end in alliances or lead to war.

Civilization was designed by Sid Meier and Bruce Shelley following the successes of Silent Service, Sid Meier's Pirates! and Railroad Tycoon. Civilization has sold 1.5 million copies since its release and is considered one of the most influential computer games in history due to its establishment of the 4X genre. In addition to its commercial and critical success, the game has been deemed pedagogically valuable due to its presentation of historical relationships, and one of the greatest video games ever made by several publications. A multiplayer remake, Sid Meier's CivNet, was released for the PC in 1995. Civilization was followed by several sequels starting with Civilization II, with similar or modified scenarios.
