just a quick explaination for those of you who don't know...SW: EaW is an RTS where you basically build troops, bases, mining facilities, star destroyers, heroes, and so on there are 2 type of battles, land battles and space battles, those are self-explanatory, each squad has their own special ability, like snowspeeders using tow cables.
forgot to say but this takes place during the Galactic Civil War...or episode 4,5, and 6...
question is though, i bought it from the store and i've seen it on steam so...if i install it will i be able to use steam with it or no?
