I like how people arn't counting Wii Sports now... when it's actually most relvent. Sure every system comes with Wii sports but people are still buying party games in addition to that. What's that tell you?
People like Party Games.
Is that actually a problem? I like party games. I'll probably get Carnival games at some point. I mean my friends and I used to play the minigames on Pokemon stadium all day.... and we were like 19 at the time. I have friends who play Mario Party to this day... the gamecube ones. They say 8 sucks...
My one friend almost got into a fist fight over Mario Party 7 when a Boo stole his star at the last minute to let someone else win. They had to institute a "No Boo's rule."
Casual my ass, if you are about to throw down because of game, it's no casual game.
