Imagine, if you will, a time traveller with nothing better to do, going back and holding a meeting with the heads of both Electronic Arts and Activision. To these powerful men, sitting atop their corporate towers, he shows a game. A screenshot of an almost comically simple landscape, populated by blocky little men and monsters. He tells them that some day, this will be the usurper to their shared throne. That some day, people will desire this more than shooting terrorists, or kicking footballs. They laugh, they mock, they call security. It seems impossible, doesn't it?
