Sid Meier's Civilization Revolution is a 4X, turn-based strategy game developed in 2008 by Firaxis Games with Sid Meier as designer. It is a spin-off of the Civilization series. The video game was released for the PlayStation 3, Xbox 360, Nintendo DS, Windows Phone, and iOS. A Wii version was originally expected but was cancelled. The absence of a PlayStation Portable version was attributed to a lack of development manpower.

4X is a subgenre of strategy-based computer and board games, and includes both turn-based and real-time strategy titles. The gameplay generally involves building an empire. Emphasis is placed upon economic and technological development, as well as a range of military and non-military routes to supremacy.
