When players play the Sims it's interesting because they'll tell stories about what they're doing in the game and they'll talk about, Oh you know I made this little guy and then he got a job and then made some friends, and then I bought a big-screen TV, and I went to bed, and then I lost my job because I slept too late, and then they'll talk about, so they're very subtly shifting the pronoun from him to I and then back again. And then to another character. And then that character will become I and you can tell that their identity has been basically possessing characters, different characters at different times. And this is something that I think that we've- I think that the basis of a lot of storytelling, the fact that we find that enjoyable, is empathy. The fact that we can watch another person, or hear a story about another person, and imagine our self in their place very easily. It's actually kind of remarkable how easily we can empathize with somebody else.
