Nintendo have described why making the jump to Wii U development has been a challenge for the company.

With the Wii U being the company's first steps into HD, the hardest part in developing software for it was the expectation and anticipation of the graphical leap - it "could not be an advantage," said Genyo Takeda. He also admitted that the company "are still having a hard time" making the best use of the GamePad controller.

That said, Takeda praised the company's efforts in ensuring that the Wii U had "hardware efficiency", something that is in "our DNA." It's this focus and refinement that the senior staff would like to "pass on to our younger developers", so that Nintendo can "continuously produce unprecedented entertainment" in the future.

Do you think Nintendo can realise more ways of using the Wii U GamePad?
