Nintendo's legendary videogame designer Shigeru Miyamoto is lying face down on the floor in Kyoto, Japan, hobbled by a right cross and struggling to regain his composure. The man some credit with the very existence of the $30 billion videogame industry, the Walt Disney of our generation, has taken one blow to the face too many. I'm standing over the creative force behind Donkey Kong, Super Mario, Nintendogs and his latest worldwide sensation, the Wii. I goad him to get up for the rest of his beating.
