Rising seas and economic volatility affect a city’s residents differently, exaggerating existing social inequality. How do we cooperate or compete in the face of risk? Bartertown is a board game that tests how cities and people can survive, and even thrive, in a crisis. It imagines a world without money to test how social networks can be re-shaped by an economy of favors and resource-sharing. Players conduct activities and adapt to oods, res, or a new romance—all while negotiating for a couch to sleep on or the chance to build ood-protection infrastructures.
