Nope, its sufficiant to note that KotOR and other SW games have sold better than they should have otherwise.
KotOR was also released on the crest od SW D20, even the SW lable isn't a constant.
There are other factors as well, the lack of any competition for instance.
KotOR is an OK game, not as good as max paine, and certainly in the classification of CRPG's its pretty poor, its really an adventure game.
SW lable is a huge boost to sales. It makes a mediocre game sell like a good one and a good one sell like a great one.
