Nintendo should partner up with Crytek UK to make Timesplitters 4 happen. That's the only "classic"-style FPS I'd accept, because unfortunately the gameplay from many older PC and console FPS games is severely outdated.

I should clarify - by "classic FPS type game", I don't mean "older-style-FPS type game". I mean an FPS game with FPS gameplay and FPS multiplayer, with the fundamental rules being FPS rules. In other words, not something like Metroid Prime, or a paintball game.
