"Stories are the filter through which we understand the world." Those philosophical words come from Susan O'Connor, a writer who's worked on BioShock, Far Cry 2 and Gears of War. In the TEDx session above, O'Connor discusses how her work scripting characters for video games led her to an epiphany about the people who may not be the heroes in their own lives. It's a surprisingly poignant talk that could make you re-evaluate the way you interact with people.
