"Let's be frank with ourselves. We all know that most people, most of the audience out there, is complacent. They are more than up for another evening in the reclining chair in front of a sitcom that teaches the same lessons that the one on last week did. They are very willing to settle for easy entertainment.
We call this "pop music." We call it "mass market." And games are indeed reaching this mass market, and I suppose that to a degree I am fighting the tide in arguing that that is not the ultimate destiny for games any more than it is for any other art form. The art we remember is material that opened up new vistas: whether or not it was popular at the time is largely an accident of history. Shakespeare ws a popular playwright and then was neglected for a couple hundred years. Popularity is not a measure of long-term evolutionary success."
