Personally, I don't care what era you set it in. If you do what they first did for KOTOR though, if you go to an unused time period you could make it so open ended. Look what KOTOR has done, the game, sequel and MMO, plus figures (not enough I might add), plus novels and comics. The only thing they didn't do was hit tv/movies with it. How much money comes into Lucas from starting one game??? Why try it again, it worked before, and if you make the first game good it will work again.
