When I use the term "kiddie" I use quotation marks on purpose. I don't think Nintendo makes kiddie games, but that's one criticism that's often used against Nintendo games. I think Mario is about as kiddie as CoD. Just because a game has head shots and blood in it doesn't make it "mature"

Furthermore, I think VGChartz should add a "Like"-button.
