Wow, do you even know what game we are discussing here?
KotOR sold well due to being SW, it was also helped by timing, it had no competition for its awards or sales, especially in xbox release, where most of its sales were. Since I am not a console gamer I talk only about the PC version, it is probably a better console game than PC game.
I have said it's a good game, but it's not great, if it was the same game made generic, without SW it would probably still make money, but it wouldn't stand on it's own merits to near the accolades that it had, or sales. Saying otherwise is just being a silly fanboy.
All in all, it's a combat game with mediocre combat and not much of a story. What does it really have other than SW? All you people making this silly claim that it is a great game on its own merits haven't pointed anything out that makes it a great game without SW.
