I don't play KoToR much anymore. Though, it was the only game longer than 125 minutes that compelled me to replay it immediately after completing it. It's a real crime it didn't get Game of the Year.

My first game, Bob of Earth, I played mostly light all the way through.

My second game, Erika Revan, I played so balanced that I was at dead center of light and dark when I reached the point of no return. (I ultimately chose to kill Bastila. Really dissapointing when she was there, alive, in the ending cinematic.)
