Sid Meier's Civilization 5 is a turn-based strategy game in which the player leads an empire from prehistoric times to the future era, conquering, allying, and trading with other civs in the game. It had a single player mode as well as a multiplayer mode, both of which can be customized heavily through mods and countless game settings.
"Civilization 5: Gods and Kings" adds religions and espionage as two primary components of the game. Religion allows you to choose specific beliefs of your empire's religion, providing perks to both the founder and followers. Espionage allows you to station spies in cities to view what rival civs are doing, sway city-states, and kill enemy spies.
"Civilization 5: Brave New World" adds multiple elements to make the late game more interesting. The ideologies of Freedom, Autocracy, and Order become more relevant in how global politics play out. A world congress acts as an open forum for introducing resolutions that impact all civilizations. A new trade route system and archaeology will add more depth to how your cities work, as well as adding a revamped culture victory.
