Naturally, being me I read it and thought about games. Because I always think about games? Hmm. I do have other hobbies, really. With the advent of more and more sophisticated choice based/ morality meter/ ethical dilemma games, I think this quote has a lot of relevance in games. Through the choices we make in simulated RPG environments we can learn a lot about ourselves. Even in other game types, like strategy games, this is true. Are you aggressive or defensive? If you're playing Civ 5 do you research wonders early, or go straight for the mass armies?
I think that when Bakhtin wrote this he was implying that it is through our interactions with people that we learn more about ourselves, but I was intrigued at the substitution technology can take for human interaction in this regard. So I decided to draw a picture about my thoughts on the matter:
It's meant to be a little ironic.
