This expansion added seven new civilizations to the epic game, and including the eight civilizations from Play the World this brings the total number of playable civilizations up to thirty-one (the maximum supported by the game). The new civilizations are Byzantines, Dutch, Hittites, Incans, Mayans, Portuguese and Sumerians. In addition to these playable civilizations, graphics and text for the Austrians led by Charles V are present in the editor so one can replace an existing civilization.
