KotOR II was far from "sucking." The game was just forced to release unfinished. In many ways, it greatly improved upon KotOR. Much of the story was cut out and chopped up to meet the release deadline, but the TSL Restoration Mod restored most of the lost content and makes the game way more complete, as it was intended.
Well, it has a nice way of complementing the first kotor, i supose, but I think revan will always be my favorite Sith/Jedi also in the second Kotor, the draw of the darkside just isn't there like it is with revan. Plus, the sith lords that play the ultimate darth juist aren't as oposing, although i liked that you could level up passed 30.
