I adored Kotor 1 it's one of my best games. It had a good solid story with one of the best WOW revolutions. It had interesting chars with past to find out, it had many npc's, enought planets and quite well quests. What's not to like?
Okay it was at someplace clitche...but on one hand Star Wars galaxy is based on fairytales, it "has" to have some clithes. The good thing about Bioware is that they managed to create a full of life game.
Kotor 2? I believe (even without the cutted scenes) is better than Kotor 1. It is far more deep that the first. It gives far more dimention to the characters, even to Revan, and takes us on a "frightening" trip back to the wars and their consicensies(?). I love it. It's so....Gray. :D
