With Wii Play, Wii's total is 36.2M, btw.
Wii Sports, Wii Play and different launch periods do make a comparison unscientific.
But its still pretty illustrative. It shows how much shooters are thriving on 360, how much mini-games are thriving on Wii, and how GH thrives anywhere. A difference can be seen in first vs third party success, as well as exclusive vs non-exclusive games. Good stuff.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
