VMS Empire is a simulation of a full-scale war between two emperors, the computer and you. Naturally, there is only room for one, so the object of the game is to destroy the other. The computer plays by the same rules that you do. This game was ancestral to all later expand/explore/exploit/exterminate games, including Civilization and Master of Orion.
