Greg Trefry has worked on many popular indie games and is one of the founders of the Come Out & Play Festival, which brought highly creative, engrossing city-wide games to the streets of NYC (2006) and Amsterdam (2007). After studying English and fiction writing at Northwestern University, Greg moved into interaction and data design. While working at a financial information company and one day staring at a database diagram too long, he became obsessed with the ways information, systems and patterns create narrative and help people understand the world around them. From this psychosis, games were an obvious next step. Greg earned a Masters degree at NYU's Interactive Telecommunications Program where he focused a lot on games. The idea of rule sets grabbed hold of his brain and refused to let go, leading him to design experiments with everything from board games to large-scale urban games, like Payphone Warriors. He has spoken at conferences about location-based games and taught workshops on game design. He is currently obsessed with modern office folk games.
