Jane McGonigal asks: Why doesn't the real world work more like an online game? In the best-designed games, our human experience is optimized: We have important work to do, we're surrounded by potential collaborators, and we learn quickly and in a low-risk environment. In her work as a game designer, she creates games that use mobile and digital technologies to turn everyday spaces into playing fields, and everyday people into teammates. Her game-world insights can explain -- and improve -- the way we learn, work, solve problems, and lead our real lives.
