The only character in the films that looks nearly as hidious is the emperor. Even Darth Vader without his mask looks much better than my character in KOTOR2. Count Duka actually looks normal, he isn't a particularly handsome man but he hasn't a SKIN SICKNESS.
The game gives you choice between dark and light side of the force, so both should be equally rewarding for the player depending on his or her personal preference. And if I play DS I feel SORRY for they guy!!! Like "oh come on man, don't die now, just drag on till the end of the game and than go to the hospital and get cured" <---- thats how I felt.
EDIT: And it might seem weird to you but I actually restarted the game when I saw the DS "Jesus" face, so I changed it. DS Jesus just looks completely obscene with his usual expression of "joyful surprise"
