I'd say something like more ships, more units probably....maybe something like a new "Clone Wars" thing where you can advacne your tech to ROTJ: 1. Start Out At Pre-Phantom Menace. 2. Advance to the PM, with new tech like "rapid fire blasters" and such. 3. Advance to Clone Wars, with new tech and units including: Frigates, Advanced Fighters. 4. Advance to ROTS, etc. each time gaining new tech and units. 5. Also you could have something Battlefront 2-ish with Republic turning into Empire. It could also be where it is Separatists vs. Republic, then it would be Rebellion vs. Empire. 6. It would be a battle of tech and tactical supremacy. But these are all just my thoughts. These would influence gameplay because harder difficulty= more fun, tech seems exciting. Oh, and I'd like to see it from Summer-Autumn.
