ok, FINALLY got kotor2 working on vista 64bit, but dear LORD it was a pain! I had to reinstall the game and fiddle with the sound properties that you can change from the game launcher. Furthermore, i can only get this to work when running the game in windowed mode then maximizing it once the game starts running. ALSO, it doesn't support widescreen resolutions, so all the characters look super wide!!!
And you wonder why people are turning to the consoles in droves? It's because a huge percentage of the potential market is just plain scared to even attempt buying a pc game.
