The Age of Kings is set in the Middle Ages and contains thirteen playable civilizations. They are the Britons, Byzantines, Celts, Goths, Teutons, Franks, Mongols, Chinese, Japanese, Persians, Saracens, Turks and the Vikings. Players aim to gather resources, which they use to build towns, create armies, and ultimately defeat their enemies. There are five historically-based campaigns, which constrict the player to specialized and story-backed conditions. There are three additional single player game modes, and multiplayer is supported.
