The reason I didn't include Play & Fit are for a few reasons:
Play - It's a $10 game bundled with a $30 controller.
Fit - Probably will sell more. The reason I argue against Fit on the list is for the game purists out there. I don't have a problem including Wii Fit on any list, but to prove a point, I figured we could exclude it :)
Back from the dead, I'm afraid.
