Playing our way to a better world

Not many people think our Big Problem is that we don't play enough games. But game designer Jane McGonigal says that's exactly what we need to do. Even she describes this idea as "crazy," but she's also got a great point. What if all the time we spend playing games was dedicated instead to making the world a better place? And what if we could do both at the same time?
