"Catan" claims to have the best "Settlers of Catan" artificial intelligence to date, featuring thirteen unique AI personalities for single player play and multiplayer games with fewer than four humans. Each AI personality, portrayed by a likeness of a famous leader or general (e.g. Abraham Lincoln, Alexander the Great, Cleopatra, etc.), has attributes such as their preferred strategy for winning, how quickly they like to expand, and their favorite resource. Three difficulty levels (easy, medium, and hard) control the level of expertise displayed by these opponents.
