You showed the Zelda trailer and that’s such a huge world. How is that going to be for you guys to approach as far as gameplay and story, because it’s such a huge world.
With Zelda games, what we’ve always done is try to make them where you enter this big world of Hyrule and there’s a lot to explore and discover, but because of the hardware limitations, what we’ve had to do is segment off each area and piece those segments together in a way that make them feel like a big world. Now, with the hardware capabilities of Wii U, we first started by saying if we can take an entire world the size of the world from Twilight Princess, and make that the size of one of the areas in the game.
Do you see that as a game where people will go to complete a certain mission and they end up doing fifty things along the way?
Yeah, there may even be times where you forget what your goal is, because you are doing other things on the side. There may be times where you go in to one big one long dungeon, or you’re headed for a dungeon and doing other things on the side. What we’re trying to do is design it in a way where you don’t have to play it for a super long time, but more matched to today’s lifestyle where you can think for a little bit, and say “maybe I just want to play for a little bit today and do this one thing.” and get that thing done, then take a break.

All sounds very promising,... and huge.
