Live-action role-playing (larp) combines face-to-face improvisation with game rules to create collaborative, playful narrative experiences for the participants. While many larps are created purely for entertainment, a growing number of larps strive to affect players. These larps include educational larps, larps for mental or physical health, larps for social change, larps that convey political points of view, and larps that ask players to explore ethical or moral quandaries. This project explores how larp impacts its players, with an emphasis on how larpers use technology in multiple roles within larp, including as players, game designers, and game organizers.
