We have already been told that the world for Zelda U is going to be pretty big, what we don't know is exactly how big, recently Eiji Aonuma spoke with Gamereactor magazine, he delved a bit into the sheer size of the world:
A huge, seamlessly unfolding world is something that can’t be achieved if the hardware isn’t advanced enough. Ever since we made the very first generation of Legend of Zelda games though, we’ve had as large a world as can be realised with the hardware, so you could say it was inevitable that we’ve now done the same with the new Wii U title.
When I first showed off the new Zelda game on the Wii U, it seemed everyone was very excited and started proclaiming that a Zelda game had at last become open world! Zelda games have always allowed you to roam and explore a huge world.
What’s changed now is that the hardware has progressed to the point that you can now explore this vast world seamlessly; the underpinning of the game hasn’t changed.
Continuing with the interview, Aonuma also talks a little bit about the implementation of the Wii U Gamepad:
Recently, I’ve taken to relying on the map on my smart phone when I’m out walking in a place I’m not familiar with. A map isn’t something you keep tucked away in your bag, it’s by holding it in your hand and being able to constantly check it as you move forward step by step that gives you that sense of adventure.
You can read the rest of the interview in the new issue of Gamereactor Magazine, which is out today.
Zelda on Wii U is expected to come out sometime in 2015.
