But... He died... He's dead... How are they adding to the Star Wars time-line by perverting it? So, either this is a prequel (which makes no sense because he didn't have any moral dilemma's before midway through the first game and Vader says "you are a shell of your FORMER self), a sequel (again, no sense because he's dead), or some sort of edition to the first game's timeline (which doesn't make sense to me either because you follow his every move)...
First game was good, not as good as it could have been. I wish they'd just make another KotOR already.
