Some kinda fun quotes from Mr. Miyamoto in a Verge interview:
"It’s a little bit less of my own experience and more of me witnessing other people," Miyamoto said. "A perfect example is my wife. When I give her video games or game systems, she doesn’t play a whole lot. But I watch her on her smartphone, and she does a lot of those types of things on her smartphone."
On kids:
If Mario is going to live forever (or at least longer than the rest of us), he’s going to have to be a part of the lives of people born well after the 1980s. Miyamoto noted that there was a point in time when "[Nintendo’s] hardware system was really the first device that kids would interact with, and that’s starting to shift." The first device kids interact with now, he says? Their parent’s smartphone. This notion of the smartphone "being the first place this kids are encountering games, is what helped us to decide to bring this to smartphones," Miyamoto said.
No shit that's "starting to shift", lol.
