I owned a 360, notice the past tence. The games were "o.k." The main game I had the 360 for is Halo 2 and 3 when it's released. Even that got old after a while.
Atleast the wii, with it's "simple wrist movements" put you more into the game than any other system i've ever played. I don't see you doing things with any other console remotes that actually have an affect on the game play. Just boring old mashing of buttons. Atleast with the wii the human aspect of a game is actually a factor, making each time you play a game, it's a different experience. Bowling is a great example of this.
