That's why I'm wondering. It's selling, but how long is it going to please people? You already hear the constant gripe of gamers saying that there's hardly any appealing games for the Wii, and all that's coming out is lame party games.
When I see things like Wii Fit, Wii Sports and Wii Music, I see those games are something you can just easily pick up and play. That's it. They'll entertain you for maybe 20 mins, and then you're done until the next time you're bored or whatever.
