"Many popular games tap into something in a person that is compulsive, like hoarding … the need to make progress with points or collect things. You sit there saying yeah-yeah-yeah and then you wake up and say, What the hell was I doing? You can call that kind of game fun, but only if you call compulsive gambling fun … I used to value the ability to turn the user into your slave. I don’t anymore."
