I also loved Star Wars Supremacy. I spent days (weeks?) playing it.
There's a guy "Slocket" on SW:rebellion

trying to remake the game but update it.
I also played Knights of the Old Republic and Empire at War to death.
Great games, KotOR was so absorbing, it felt like a "real" Star Wars story. They could be the basis for excellent films, sufficiently different from the original trilogy.
