Not sold on Wii?
Game World Network has compiled a list of E3 videos which show both the action on screen and what the player is doing off the screen. That way you can see how the players movements translate into movements in the game. It's very interesting to watch especially if you're not sold on the controller yet. No wild arm flailing like they showed in some of the official trailers, just slight wrist movements is all that's needed. They have videos from pretty much every game that was playable on the show floor.
