My problem with this gimmicky stuff is that everything feels like a dumb little arcade game that you play for 10 minutes and move on. Nothing has depth anymore. Honestly, I don't have much experience with the Wii but I can tell that they're really focusing on all these novelty multiplayer diversions at the expense fully fleshed out single-player games. But, yeah, I guess if you want that you go with PC games.
