Miyamoto explained in a recent YouTube interview, translated by Nintendo's Bill Trinnen, that even though Zelda game's have always been about exploration, "Because of the hardware limitations, what we always had to do was segment off each area and piece those segments together in a way that made them feel like a big world. But now with the hardware capabilities of the Wii U, what we did is we first started by saying, 'Let's see what we can do if we take an entire world the size of the world from Twilight Princess and just try to make that as one area in the game."
The game will also be broken up into chunks to make shorter play sessions more manageable.
"What we're trying to do is design it in a way that you don't necessarily have to sit down and play it for a super long time," Miyamoto said. "But, kind of, more matched to today's lifestyle where you think for a little bit and say, 'Maybe I just want to play for a little bit today and do this one thing, get that done, and then take a break.'
While details were much more scarce for other upcoming games, Miyamoto also talked about next year's Star Fox game. Amiibo will have some interactivity with Star Fox that he hopes the player will "get some enjoyment out of."
And Miyamoto confirmed online functionality for the make-your-own-Mario-game Mario Maker. "You'll be able to see what happens when other people play your course or when you play other peoples' courses. There'll be popularity rankings for the most popular courses and things like that. So there's a lot on the community side that you can look forward to." While he explains the main draw is local co-op, he says, "Of course, we'll have the Internet ability to exchange courses as well."
