Sid Meier's Civilization V

Sid Meier’s Civilization V is a single-player and multiplayer turn-based 4X strategy game. As the ruler of a fledgling nation, the player begins with a lone settler and a warrior in an unexplored world. From this starting point the objective is to expand, discover, negotiate, and if necessary fight, guiding the civilization across eras while pursuing one of several paths to long-term dominance. Rival leaders develop their own empires at the same time, so exploration, diplomacy, culture, science, and military planning must be balanced to reach victory.

Play takes place on a hexagonal world map that replaces the square tiles of earlier entries. Each hex represents terrain such as plains, hills, forests, or coast, and provides yields of food, production, and gold that determine city growth and construction speed. Fog of war hides the map until units explore it. Strategic and luxury resources appear on specific tiles. Strategic resources such as iron and oil gate the production of advanced units, while luxury resources increase empire happiness, which affects growth and productivity across all cities.
