It sounds like a backhanded compliment, but really the "Mario & Luigi" RPG series (Superstar Saga, Partners in Time and Bowser's Inside Story, thus far) for portables have probably been the story/humor highpoint for Nintendo franchises for the better part of the last decade. Sharp, funny, self-aware, perfectly balancing sincere "quiet awe," unobtrusive fanservice and a knowing self-awareness. The first 3DS installment has now been announced as "Mario & Luigi: Dream Team," with the now-standard alt-dimension storyline taking place partially in the realm of Luigi's dream...
Dream-world, eh? Hm...
Nintendo? I don't ask for much - which is good, since you're kind of the opposite of generous when it comes to this stuf... But if Wart (the dream-world heavy from the U.S. SMB2) turned up here in some capacity it would make me just about the happiest boy in the world. Bonus points if he brings Mouser, Triclyde, Fryguy, Clawgrip or any combination thereof with him.
