I first played Morrowind on the Xbox so even though I have it on PC I always prefer it on Xbox. I actually still own my old Xbox (gotta be one of the few in the world still running) and I play it on that because it plays like crap on the 360.
Don't see why you would think that... The original xbox was pretty well build and there are prob hundreds of thousands still in working order, including mine.
Also, I have no idea how you can prefer this game on the xbox. I have the game for both, and the PC is better in everyway. On the xbox, the loading is INSANE. Also, the draw distance is so bad, it is like you are in a world surrounded by fog. Morrowind is a lot better with texture replacers, face replacers, and better bodies.
