You must be playing non-stop :u
I like Birdo because he was such a freak, but I don't really care about Waluigi. While I'm disappointed with Metal Mario (Tanuki Mario would have been better imo), I think the roster is fine as it is.That's a shame, I always lived in the hope that, in order to freshen up the game in the future, we would be able to download new characters. Waluigi's, and even Birdo's, presence has been sorely missed in this game, only to be replaced by that insufferable Lakitu and a powerup.
Spread the word.Also, I would have loved Luma to have been a character.
