We only have a limited amount of data in our lives; we only have a limited amount of experience that we'll ever have, so we found ways to supplement that. One of the ways is by building kind of these little toy experiences- things we can kind of abstract into real experiences but we're playing at a toy level. And you know, we've come to call this play in games. Another way to kind of supplement this experience is to learn from other people's experience. Someone else can download their experience enemy, and they can use that to refine our world model. And we call that storytelling. And so I think storytelling and play are both educational technologies, and that's why we find them satisfying, because they actually allow us to build more elaborate models of the world by supplementing the limited experience that we'll have.
