Sid Meier's Civilization V is a 4X video game in the Civilization series developed by Firaxis Games.
The
    game was released on Microsoft Windows in September 2010,[3] on OS X on November 23, 2010,
    and on 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.[5] 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.[6] 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,[7] and roads now have a maintenance cost, making them much less common.[8] The
    game features community, modding, and multiplayer elements.[5] It is available for download
    on Steam.
    Its first expansion pack, Civilization V: Gods & Kings, was released on June 19, 2012, in North
    America and June 22 internationally. It includes features such as religion, espionage, enhanced naval
    combat and combat AI, as well as nine new civilizations.[9]
    A second expansion pack, Civilization V: Brave New World, was announced on March 15, 2013. It
    includes features such as international trade routes, a world congress, tourism, great works, as well as
    nine new civilizations, eight additional wonders, and three ideologies. It was released on July 9, 2013,
    in North America and in the rest of the world three days later.
