An official standalone game was made using the game engine, dubbed Sid Meier's Civilization IV: Colonization, which remakes the 1995 game Sid Meier's Colonization. All the content from Warlords (with the exception of the expansion's scenarios) is included in Beyond the Sword (which also includes twelve custom mods, ranging from historically accurate to medieval fantasy to science fiction). Both expansions add new civilizations, leaders, units, and buildings. The game received two official expansions over two years: Sid Meier's Civilization IV: Warlords (adding gameplay mechanics based on war dominance) and Sid Meier's Civilization IV: Beyond the Sword (adding various new gameplay mechanics, from the concept of corporations to random events). The fourth installment of the Civilization franchise, Civilization IV builds upon the gameplay from Sid Meier's Civilization III, adding 3D graphics, a simpler user interface, reasonable (and more transparent) AI players, and other gameplay improvements (including the concept of religion, improved military unit promotions, the more flexible 'civics' model (replacing the simple 'governments' model), and the concept of 'Great People'). Sid Meier's Civilization IV is a turn-based 4X strategy game developed by Firaxis and published by 2K for the PC on October 25, 2005.
