Miyamoto gets a dog, makes Nintendogs. Miyamoto starts weighing himself for fun, makes Wii Fit. See a trend? It wasn't always that way! While his earlier games were influenced by his life and experiences, they were influenced abstractly — more make-believe, less reality. According to Miyamoto:

I would say that over the last five years or so, the types of games I create has changed somewhat. Whereas before I could kind of use my own imagination to create these worlds or create these games, I would say that over the last five years I've had more of a tendency to take interests or topics in my life and try to draw the entertainment out of that.

Every artist goes through phases — even Shigeru Miyamoto.
