Meier stopped to think of three innovations more important than anything else in gaming history. The first, he mentioned was IBM making a personal computer. Another was the development of “Sim City” and other games that encouraged construction, rather than just destruction. The third, Meier said, was Nintendo’s Official Seal of Quality; a 1980s stamp of gaming quality that he said helped counter the flow of bad games that had drowned so many previous video game consoles.
