Heck yes. I've beat it on hard so many times that I and play the whole game without saving or dying. I have had to invent new ways to play just to make it challenging.
Try the all weapons cheat code and use only the saber for the whole game. There is nothing more creepy than standing your ground in front of a Kell Dragon, Swatting it with your saber, and quickly moving outta the way. Or running up on a Rail Gunning Storm Trooper, jumping over his charges and killing him before he hits you.
