There are games and programs it wont work with.
What those games are I couldn't say.
Not because I don't want to.
But because you are gay.....

Sorry... it just rhymed to well. I really don't know all the games it won't work with. But I remember hearing that there are a few. Your best bet would be to try it. Or name a game and see if anyone has had any experience with it. Don't expect a list of games that it doesn't work with... as there are a LOT of games out there and most of us only purchased KC to work with WoW.
