Simple. I didn't know a thing about D&D universe and I still enjoyed games like BG, IWD and NWN, so why not have a go at KotOR?
Why don't I watch the movie? Gee, I don't know. I didn't like what I saw so far about SW universe in KotOR and people around me aren't exactly SW fans. I'm not going to watch a movie I may or may not enjoy by myself. I'm sorry, but the whole Jedi thing doesn't really appeal to me and also lightsaber makes me laugh (glow stick…). Then again, I liked Harry Potter and they duel with wooden sticks….
I'm thinking of having a go at KotOR2 instead and see if I like that one better since I really liked some dialogues (watched few youtube vids).
Well, at least I'm glad I'm not the only one finding KotOR1 boring. I will try to make a bit more progress with KotOR1 though. I'm currently at Tantooine, the first planet I've landed ever since leaving Dantooine.
