Oh gawd, you corey core gamers of hardcoreness with your macho corey comments. Those who make these absurd comments, have you even played this game? This is one of the games I always start at least once when I have people over and it's a blast.
However, it seems no one in this thread has understood why this game is selling so well.
Part of the reason is that it's a fun party game with a great concept. However, that's only part of it's success. This game is also bought by people who use their Wii's for exercise. I'm one of them. You know how they say it's healthy to move at least 30 minutes actively every day? Believe me, this game makes it really easy. Dance to a few songs and before you know it you've been moving for an hour, having trouble to breathe :lol
It makes moving fun.
I will buy Just Dance 2, 3, 4, 5 just for more songs in a heartbeat. This is actually great software with some actual thought put into it.
