How would controls work though for Perfect Dark or even Goldeneye!! The classic controller is no N64 pad replacement, look at the Z trigger placement etc.
Hell I'd buy it though awesome game.
Don't know that a HD version would be particularly impressive without some sort of graphic overhaul, which wont happen (some upscaling would help).
Banjo is also a good game, but if Goldeneye and Perfect Dark became available it would be truly awesome!!
