A kind of entertainment makes us adict with the combination of game-play and ego-stroaking reward? His co-worker, Avellon also mentioned the importance of ego-stroaking. And somehow, I think he meant not only power-gamers.
I think critical thinking is more of common sence and feel bit patronized but I guess a part of his intention is to point out too many gamers mix up their tastes with game mechanics. He made a good point by mentioning ego-stroaking factor. Some gamers feel smarter only because they play games of their liking. Watch out how your favourite games play with your mind! But as a game-designer, isn't he responsible for it?
