There was something of a divide between gamers who preferred the Wii and those that preferred the PS3/Xbox 360. Nintendo president Satoru Iwata and designer Shigeru Miyamoto hope to bridge the gap between casual and core console gamers with the Wii U.
“This is something that has been pointed out by developers outside of the company. Including HD support, there had been times up to now where you could do things on other companies’ hardware, but was difficult to do on Wii,“ said Iwata. “With Wii U, I also wanted to alleviate those restrictions as much as possible.”
“One of the key reasons that such things as the core and the casual exist today is that we decided not to adopt HD on the Wii console. Of course, besides that there are things like issues with the controller and the challenges that it brings, network functionalities and many other things, but I think HD was the biggest factor that everyone was able to clearly understand the difference,” said Miyamoto. “In terms of the HD capabilities, Wii U can do something similar, and on top of that, it is equipped with this new controller that adds an entirely new structure to games. I think this is an opportunity for those games that were considered to be core up to now, to evolve into something even more interesting, structurally.”
