The mechanics of the game are simple. Each player assumes the role of a totalitarian ruler of a small galactic empire. Every player in turn examines status reports and issues orders each year, a simple process that includes determining which worlds can become colonies and deploying fleets to conquer them. Once all players have taken their turn, the computer updates all the worlds in the galaxy and the next year begins. There are no formal victory conditaions in the game, so a game doesn't ever have to end.
