When Amy Green’s young son was diagnosed with a rare brain tumor, she made up a bedtime story for his siblings to teach them about cancer. What resulted was a video game, “That Dragon, Cancer,” which takes players on a journey they can’t win. In this beautiful talk about coping with loss, Green brings joy and play to tragedy. “We made a game that’s hard to play,” she says, “because the hardest moments of our lives change us more than any goal we could ever accomplish.” This video tells you about the creation of the game, and how it can help you through your grief. It has a beautiful message about what impact love and loss has on your life.
