The story is bar none, one of the strongest features of the game, and makes games like Halo and Gears of War pale in comparison (strictly on story issues).....
I just finished it last night on the "regular difficulty" (not easy, but one step up). Star Wars games have been freakishly hard, even on Regular, and that trend continueshere, so you may want to play it on easy if your button mashing skills are average..... The boss battles specifically are exercises in frustration (the worst being when you spend 20 minutes finally beating one boss after 10 tries, it throws a second boss at you which kills you in your weakened state, and then you have to go back and fight the first boss again.... Grrrrrr.... Oh for the good ole days of Doom that let you save at any point in a tough section.....
But the cutscenes are gripping (I especially like one after you fight Darth Vader near the end)....
One annoying part of the game? The much hyped yanking down of the Star Destroyer on the junkyard planet..... Way more annoying than it should have been.... After you fight off a dozen TIE fighters, you turn the Star Destroyer for 40 seconds and line it up, ... as SOON as you get it straight and start to nudge it downwards, they launch another dozen TIE fighters at you. Ignore them and they shred your health, let go of the Destroyer and it starts turning again and you have to start over again......
I'm looking forward now to going back to the earlier missions at full strength and getting the missing holocrons and bonus objectives....
One GOOD thing I like...... When you fail a section, it DOESN'T subtract any level ups you've achieved or talents learned..... So if it takes you 10 times to beat a foe, you get incrementally stronger.... However, it's not like KOTOR, where you are bordering on godlike at the end of the game... You never quite feel like you are invincible....
