Difficulty level (Civ3)

The difficulty level is a game setting in Civilization III that allows players to compete against AI opponents matched to their skills and desire for challenge. In order from lowest to highest, the difficulty levels are as follows:
* Chieftain
* Warlord
* Regent
* Monarch
* Emperor
* Demigod*
* Deity
* Sid*
* Available with Civilization III: Conquests.
Since the computer players are not controlled by advanced AI (i.e., cannot learn from and react to the player's strategies by changing their own accordingly), but instead behave based on a very long list of if-then statements, the game makes the AI leaders more challenging opponents by giving them advantages on higher difficulty levels. The bonuses conferred to both human and AI players on each difficulty level are listed in the table below.
