Superstruct is the world's first massively multiplayer forecasting game. What does this mean? As a player of this alternate reality game, you envision your life as it would be in 2019 and collaborate with other players to come up with innovative solutions to global 'superthreats'. These superthreats may bring us to a tipping point that determines whether the human race either solves its looming problems and continues existence, or society collapses under the weight of its troubles.
The excellent sci-fi centric io9 has an interview with futurist Jamais Cascio, a member of the Superstruct game design team. Cascio discusses his work on "21st Century Ideas" (essentially a toolkit of solutions to the game's superthreats), the influence of Children of Men on the game and its setting, and some of the innovative creations he's seen from players in the relatively short time since the game launched. It's definitely worth a read if you're interested in a game grounded in futurist speculation. If this piques your interest in Superstruct, don't wait to find out more -- the game will only run for another 5 weeks. Be sure to check out Massively's primer on Superstruct to help you get started, as well as Jane McGonigal's Avant Game blog for more info about the game.
