The one and only classic star wars galaxy 'builder'
Set-up is in 3 different difficulties. Colonize the outer-rim planets. Confince the core systems to join your alliance by diplomatic power. Force out the other party by winning battles, but make sure to do enough research to tip over the balance of power to your side and create a massive indestructible ground force, combined with a fleet comprised of all the ships you ever saw in any movie (not including the ep.1-3 ofcourse)
If you like 'world-builders' and star wars, this is still a pretty good game to play. Not too hard, and not too shabby (i'm still not 'tired' of the graphic lay-out ;)).
Downside of the game: the rather annoying management interface through which to 'micro-control' the universe ( all the clicking-away of every window just makes it tiresome to play sometimes). Besides the nice-looking 3d-battle screen (for its time anyways) is not always that easy to use and can be rather confusing, although using it is adviced for smaller battles to diminish your losses and inflict greater losses on the enemy.
