I went though the first playthough on medium difficulty and didn't have any problems at all. Campain is SHORT and you are basically on two worlds, but I suppose the challenges they added are supposed to make up for that. I live Jedi mind tricking dudes and having them jump to their deaths.

Right from the start of the game you feel like a Bad-MOFO-get-out-of-my-way-or-die-Jedi-Knight.
