Republic Commando, Battlefront(s), Jedi Knight(s) TIE Fighter, Xwing, Star Wars Rebellion, Empire at War, Rogue Squadron, Jedi starfighter are all good in my opinion, but need some changes to get better.
Empire: Bigger armies and battlefields and more battle options(aircraft, defences etc)
TIE Fighter/Xwing: A remake with more awesomeness.
Commando: It felt short. MOAR STUFF please.
Battlefront(s): fun, but repetitive. More/bigger maps, and some more options in the dual screen galactic conquest would be nice (more planets, buildable defences on planets etc -> maybe a mix with empire at war? -> empire building game with fps fighting? Like mount and blade(sortof)
Jedi Knight(s): fun, I guess. II more than academy though.
Rogue Squadron: One of the first star wars games I played, fun, but needs more playable ships and space combat.
I could go on, but in the end, I think I played KOTOR the most for the fun it held. It could do with the jedi knight combat system though. And I want to buy a star destroyer* with crew and raid trade routes and space ports, dammit! I wanna be a pirate.
Make a game with KOTOR-style rpg-elements and story, Empire at war sized galaxy, Jedi knight fighting style and freedom from (non-lucasarts) mount and blade and I'd happily buy the game.
