Unlike major powers, city states may expand in territory but they never establish new cities (although they can conquer other cities with military units). City-states Ĭity-states, a feature new to the series, are minor civilizations that can be interacted with, but are incapable of achieving victory. Morgan Sheppard provides the narration for the opening cinematics to the original game and its expansion packs, the quotations at the discovery of new technologies and the building of landmarks, and the introduction of the player's chosen civilization at the start of each new game. It is possible for a civilization to sign a research agreement for the sole purpose of getting an enemy to spend money which could be used for other purposes AI civilizations are programmed to sometimes use this tactic before declaring war. Prior to the 1.0.1.332 PC version of the game,civilizations were provided with an unknown technology after a set number of turns of uninterrupted peaceful relations. Two civilizations at peace can form a research agreement, which requires an initial investment of gold and provides both civilizations a certain amount of science so long as they remain at peace. It is available for download on Steam.Ĭivilizations can no longer trade technologies like in previous versions of the game, instead civilizations can perform joint technological ventures. The game features community, modding, and multiplayer elements. 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. In addition, the maps contain computer-controlled city-states and non-player characters that are available for trade, diplomacy and conquest. The combat system has been overhauled, by removing stacking of military units and enabling cities to defend themselves by firing directly on nearby enemies. 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 game is based on an entirely new game engine with hexagonal tiles instead of the square tiles of earlier games in the series. 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.
