I still play Galactic Battlegrounds every now and then. Not only that, but i play some of the oldest Star Wars games around. anyone remember Dark Forces (the original)? I still play it now and then. Also, anyone play Rebel Assault 2? STILL PLAY IT!
Believe it or not, i actually tried the demo for Force Commander. Old, but sweet. wFun.
Rebellion looks interesting. I never actually found any screenshots of a battle tho, so i dont know whats it like.
