The Crusades is two games in one. The basic game is a two-player simulation of the Third Crusade (1191 to 1192AD). The Crusaders, led by Richard Coeur-de-Lion, Philip of France, and the divided barons of the Kingdom of Jerusalem, try to regain the territory (and the city of Jerusalem) lost to the Ayubid Sultan, Saladin (the Saracens).
The second game is a multi-player simulation of the First Crusade, in which various Frankish and Norman knights and lords march to the Holy Land, each with a different set of motives to meet their opponents - a divided coterie of Muslims.
