Gameful’s aim is to attract people who “want to make or play games specifically designed to a have a positive impact on the real world, or on our real lives: game designers and developers, game writers and artists, programmers and producers, project managers and marketing experts, reporters and critics, students and researchers, players and playtesters.
Even if you’ve never made a game before, you’re welcome to join Gameful — you’ll surely find people who would love your help with their games… or who would be interested in helping you make YOUR idea a reality!”

It all sprang out of Jane McGonigal's TED talk.
