It may be old but I missed this clip. It's also rarer to hear Miyamoto use english as he seems so cozy still using an interpreter.

The fascinating thing with Mario Maker is that the menu bar up high reeks strongly of the Mario Paint interface of the SNES, and I couldn't think of a better one to ape for the present. It's mind blowing they do NOT put the rom for that out or make a real second Mario Paint as a download only (at the least) game for the 3DS. I hope Mario Maker once the WiiU version sales fizzle will pull a 'smash bros' on it and throw it on there for more penetration. I can't say I'd use it but if I did, portability would be key in that interest.
