Masahiro Sakurai is currently working on Kid Icarus Uprising for the 3DS. The producer of the Super Smash Bros series thinks that going back to 2D after working in 3D will be hard for him to do.

“Yes this is indeed my first 3D game but I have a feeling that it’s going to be hard to go back [to 2D], said Sakurai. “For example when you watch Avatar in 3D you take notice of the 3D element initially but then as the movie goes on you forget about the 3D novelty as your eyes get used to it and simply enjoy it for what it is.

“That’s the nature of the way we get used to things as they become familiar. The problem is that when you go back to 2D after 3D it feels flat. So in terms of game development I would think that going back to 2D after working on a 3D project may be very difficult for me.”
