One of the other things that gets me about Mario is... he's not Mario. The Mario we know from those incredible platformers and Super Mario Sunshine can't be the same one from Brawl and the SMS box. In Brawl, he's just so... D:< all the time. The jolliest thing he does is say "Here we go!" when you select him using a non-GameCube controller. In the game, it's all about scowling and sounding utterly unenthusiastic. I don't know WHAT Luigi is, but at least Luigi's face isn't boiling with rage.
