"In those days, Miyamoto would come to us at 11 PM, after he finished all of his board-member work, and say, "It's Mario time." At that point, we'd start a planning meeting that would run until 2 AM. At that point, Miyamoto would go home, leaving us with the words, "You should return home soon, for your health." Over the next two or three hours, we'd write the game design documents and summarize the instructions for our artists and programmers.
It was the craziest crunch time that I've ever experienced in my development career. But if the God of Games was working so much, could we give up? Miyamoto had incredible stamina."
