Most of the commands that you give your planets are 'routine' stuff. You maximize your factories, change your friendly codes (especially if you play against the Birds) and you tax your natives. This needs a lot of time and very few thinking. RANDMAX will do all these work for you completely automatic while you have still full control over your planets.
Perhaps a little more explaination is required. It is a game of planetary conquest played on a computer with up to 11 players. Players make their moves, pack up their turn and send to a host who then runs everones turns at the same time.
