The Wii U generation requires twice the human resources, and has caused longer development times.
In a recent investor Q&A, Nintendo’s Shigeru Miyamoto stated that going from the Wii to the Wii U and upgrading to HD visuals has required “about twice the human resources than before”, and he admits the company “may have underestimated the scale of this change.”
“When it comes to the scale of software development, Wii U with HD graphics requires about twice the human resources than before. Please allow me to explain that we may have underestimated the scale of this change and as a result, the overall software development took more time than originally anticipated just as we tried to polish the software at the completion phase of development.
But there is good news. “However, we are almost out of this phase, and we are also trying to create something unique utilizing an easier development approach called ‘Nintendo Web Framework.'”
Will it reduce the weight for titles like Pikmin 3 and Super Smash Bros. in the near future? One can always hope.
