The ancestor of all 4x (expand/explore/exploit/exterminate) games.
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.
