Civilization V

Sid Meier's Civilization V is a 4X turn-based strategy video game developed by Firaxis Games and published by 2K. It is the sequel to Civilization IV, and was released for Windows in September 2010, for Mac OS X on November 23, 2010, and for Linux on June 10, 2014.

In Civilization V, the player leads a civilization from prehistoric times into the future on a procedurally generated map, attempting to achieve one of a number of different victory conditions through research, exploration, diplomacy, expansion, economic development, government and military conquest. The game is based on an entirely new game engine with hexagonal tiles instead of the square tiles of earlier games in the series. Many elements from Civilization IV and its expansion packs have been removed or changed, such as religion and espionage (although these were reintroduced in its subsequent expansions). The combat system has been overhauled, by removing stacking of military units and enabling cities to defend themselves by firing directly on nearby enemies. In addition, the maps contain computer-controlled city-states and non-player characters that are available for trade, diplomacy and conquest. A civilization's borders also expand one tile at a time, favoring more productive tiles, and roads now have a maintenance cost, making them much less common. The game features community, modding, and multiplayer elements. It is available for download on Steam.
