Eurogamer Miyamoto interview: Future of 3D Mario (Galaxy)
I'm guessing in the same interview where Miyamoto confirmed Pikmin 4 he talked about the difficulty of making 3D Mario games for a large audience in comparison to SMB which everyone can play. Teases new 3D Mario for future hardware.
“[A new Mario Galaxy] is always in discussion. But even with Mario 64 there was a lot of feedback about motion sickness with the 3D or maybe us making it too difficult.”
“Going back to our roots and making New Super Mario Bros., anyone can play that. So that’s why we went back. We’re always thinking, is there a middle ground where people who do enjoy the 3D worlds of Galaxy and those who enjoy New Super Mario Bros. can both enjoy it? We’re always looking at those opportunities.”
On the other hand, me and [Yoshiaki] Koizumi-san, director of Galaxy, are always looking to challenge Galaxy and do another 3D action title. However we can’t make so many games at once in parallel. But as the hardware technology gets better and advances, I think there will be a lot of opportunity for both options.”
On the hardware that's needed, Miyamoto says:
“Wii U’s definitely good enough in terms of hardware performance, it is more the workload of the team. If you look at Star Fox Zero, the TV and GamePad are both rendered in 60 frames, so in total that’s 120 frames. It’s really just a matter of the CPU speed at this point.”
Miyamoto also stated that he hopes that Splatoon will help players come to terms with a 3D camera for the next 3D Mario and that Nintendo is always looking at ways to surprise players.
