Actually, being that his claim is "Listen, we all know the Wii is selling well, but that doesn't mean people are actually playing the console," I believe you have to include Wii Sports, Wii Play and Virtual Console games because they're being played on the console ...
It doesn't matter whether people bought these games for a lot of money, they're still being played. Certainly, someone may only put 10 or 20 hours into Wii Sports but if that is a reason for discounting a game can we stop including Heavenly Sword, or Gears of War/Halo 3 purchases made for the single player campaigns?
One of these days someone is going to have to explain to me what is so bad about games that look like:









... I've got more then 10 Wii games and only 3 are from Nintendo cuzz i hate casual games like Big brain academy and shit so i don't buy those Nintendo games... Only the Metroids, Mario's, Zelda's etc... So people ARE buying the 3th party games!
