I'd probably die if good ol' Nick was in Brawl, but then I wouldn't get to play it...
Now how would that costume work? There's only like, two separate sprites for Jumpman. Thus, he'd be a really cool character to show off how creative the guys behind Smash Bros. can be. Either way, it'd be cool, but I'll always pull for Jumpman (or 8-bit Mario, if that floats your boat) as the G&W replacement. Oh yes, he's going.
Creo: I'll stick to my SmashBoards and 4chan. Sane discussion about one of my favorite games of all time balances out horrible, horrible internets rather nicely.
