I say keep the KOTOR franchise a CRPG. If you want a Star Wars FPS then go play Battlefront, Jedi Knight O & A, or wait for Republic Commando. There is only one Star Wars CRPG to my knowledge so let KotOR stay that way.
This may have already been said but maybe Palpatine acts the way a real sith should act and every other sith is acting unsith like. The movies did come first after all.
