Wii software WW > 360 software WW. Microsoft: "Wii doesn't sell software"

[TheBigFatJ]

If you don't count bundles, you'd remove a lot of Wii Sports (but it would still have ~10 million sold, eh?) and a lot of Forza, Marvell, etc. I don't see why you wouldn't include Wii Play. The game may be inexpensive, but it still costs something.
