Super Mario 3D World may be the "present culmination of 3D Super Mario," but that doesn't mean Nintendo's EAD team is done with Super Mario Galaxy games. Speaking in a recent Iwata Asks interview, EAD General Manager Shigeru Miyamoto assured fans there could be another entry in the series that appeared twice on the Wii to high acclaim.
"The same team can't make both [Super Mario 3D World and another Super Mario Galaxy game] at the same time," Miyamoto said. "And we can't bring in a second party and slap the name Super Mario Galaxy on it. I suppose we could idealistically make both in Tokyo, but we want to do something new too, so there was that dilemma."
The same interview revealed a few interesting tidbits about Super Mario 3D World, including that fifth playable character Rosalina is unlocked by beating the main game i.e. getting the ending, and her unique ability is a "special spin attack" (see above.) Also, the cloning power-up that lets you control multiple heroes was inspired by a mistake, after an EAD developer accidentally used a placement tool to put in two Marios.
Not that it's very surprising, but 3D World Director Koichi Hayashida also noted Nintendo had the Wii U game in mind ever since it began development on 3DS entry Super Mario 3D Land. As for future Mario adventures, Miyamoto said, "Personally, I would like to take on a variety of new challenges with Super Mario Galaxy and design 2D Super Mario games in an easy-to-understand way within certain restraints."
Super Mario 3D World is out next week on November 22 for the Wii U.
