I classify it for kids, due to the fact that its pretty generic and lacks any subtle jokes or content that adults would appreciate.
That doesn't seem very definitive. I mean Brain Age is unquestionably for adults, and yet has none of the subtle jokes or "content" (assuming I'm right about what I think you think "adult content" is.) So's Wii Fit too.
It seems like it's trying to appeal to comic book fans with the generic superhero characters, but overall the design looks like a rejected Sony First Party game circa 2003. It's got that special kind of focus-tested generic that Jak has. So it's really got no heart and soul. Just another thing to lose out the better stuff that has more effort put into it, and possibly another log on the failure fire from a company who purports to "get" the Wii now.
But considering Capcom's stance on Wii support (More titles = better support than 360/PS3), we should be lucky this game even survived, I guess.
