KotOR is a great game, I liked 1 better than 2, I wish they would make a third it is nice to get Star Wars games that are not tied to the "Current" universe, and nice to get the history.
Mass Effect actually made it worth customizing a character cause you could see and hear your person talk during cinematics. In Oblivion, if you wanna look at your character, either you go to the menu part, or move the mobile camera around which isn't much fun.You should try Mass Effect on the 360. Amazing game by the guys who did Kotr1. It's probably my favorite game on the 360 yet.
