A Jabba the Hutt game, where you play as the crimelord himself. Manage his empire, control the gangstas, hire bontyhuynters to do your bidding, and feed unruley biotches to your pet rancor (or other creatures of your liking)
On the other hand, a Star Wars: Smugglers (or undrworld) game would rock. You can do gta style stuff, triple crossing crime lords, sell your spice, upgrade your ships, even do a bit of bounty hunting if you want, and best of all... PLAY CARDS AT THE CANTINA. Obviously you can do runs and things for the empire or the rebels.
Too bad knowing lucas and tinheads they would never let thsi fly.
