I actually enjoyed the first twelve or so levels. There were some moderate annoyances (that damn speeder bike level was freaking annoying), but generally it was fun rampaging through levels, cutting down everything in my path. Then I hit the second storyline mission, Darth Vader's Castle. Fighting multiple super powered-assault-armor Stormtroopers who wield the Concussion Rifle (which just kicks your ass and you can't saber block it), who bash you about 20 feet back if you get in front of them, and take 10 or so saber hits to kill. Oh, and you're fighting them outside in an acid rain which constantly saps your shields and health. That was bad enough, but in the third storyline mission when you have to fight SIX of them, at once, in a pool of lava, that pretty much did it for me.
I like a challenge, but I don't like ghey uber-monsters.
Oh, did I mention that the AI Dark Jedi *can* saber block the Concussion Rifle? Wow, that's nice.
