Quest (1981)

Publisher's blurb A new idea in adventure games! Different from all the others! Quest is played on a computer-generated map of Alesia. Your job is to gather men and supplies by combat, bargaining, exploration of ruins and temples, and outright banditry. When your force is strong enough, you attack the Citadel of Moorlock in a life or death battle to the finish. Playable in 2 to 5 hours, this one is different every time.
