SourceShigeru Miyamoto is not some lovable man-child! He used to smoke and gamble. And he gets pissed, man, he gets PISSED. Just listen to what Nintendo honcho Satoru Iwata has to say about him:
"Miyamoto-san gets pretty scary when he's angry, doesn't he?"
"Miyamoto-san is really merciless when it comes to planning!" (laughs)
Shigeru Miyamoto, brilliant game designer. Frightening dude. He doesn't just upturn tea tables. He BEATS people with them.
I think every game designer is like this at some point in their life.
