I voted Obsidian. If they hadn't cut all of that stuff about your characters in the end, this game would have been as good as the first IMO. I say Obsidian should take another go at it. With some more time, I know they could come up a good storyline for a KOTOR 3.
I loved KOTOR and KOTOR 2. Finally a game that I was looking for. I didn't want a game where it was just push the button as fast as you could to see who could get more hits on the other person. Not only that, but the lightsaber and sword duels were the most realistic looking that I have seen in a game to date. Not only this, but after the ending of KOTOR 2, I would like a little bit of closure.
On a side note. I liked that stuff about the "True Sith". It adds to the game and gives you a new perspective on what you view the Sith as.
