What is KOTOR??? Video game, book?
It's Knights of the Old Republic, a role-playing videogame that takes place I think about 2,000 years before Phantom Menace. It's really something of an interactive movie (in that despite the illusion of freedom it's pretty linear), and is so well written that it actually puts the last couple of movies to shame. Lucas should hang his head and do the dance of shame that he's been outdone by Bioware in a video game.
It's a videogame set 2000 years before the movies during the Republic-Sith war. Don't knock it for being a videogame -- it has a story that unfolds over 50+ hours of voice diolouge that, in my opinion, is better than any Star Wars movie -- even Empire. It's literally the best video game I've ever played. If you have an XBOX or PC, I highly recommend it.
