Miyamoto on maintaining Nintendo quality - Maintain a visual history, don't look like Sega or other third party titles

A portion of Wired interview with Shigeru Miyamoto…

Wired: Nintendo is huge now. How do you maintain quality control?

Miyamoto: I’m always instructing my game designers on the history of the characters and worlds we’ve created. Often we’re in development and I’ll say, “Oh, this looks like a Sega game. We need to make it look more like Mario.”
