Come to the dark side...
Built on the old Age Of Empires 2 - engine, Galactic Battlegrounds throws you into the very heart of the conflict between good and evil. You play many memorable characters, Cheewie and Mr. Vader included, and you get a tough time fighting against the empire because the AI is impressive, also the graphics, which, at the time - was the best that we could see. The maps are many and varied, one of the best graphics of the game is the implementations of the film-style from the movies. Although tiny, you see exactly what everything is.
If you love Star Wars, this is for you. Good old fun and quality time! Newer RTS should look more in the past how they used to do things, graphics is not everything that should matter.
