I don't know that I can say for sure that nVidia did anything wrong without having been at their discussions, but there is someone to blame: the game developer. Sure ATI could have sent in someone to work with them, but if a game developer can't test a feature like AA on ATI hardware, they shouldn't be making games in the first place. ATi should be able to come in to help *optimize* it, but in terms of ensuring that features as basic as AA work.. that should be something they can do.
