MIT's Game Design course (CMS.608/CMS.864, Fall 2010) turns to live action games, taught by Philip B. Tan and Jason Begy. The lecture surveys the category's range, from sports and real-time roleplaying to playground and party games, and asks what separates a well-designed live action experience from a chaotic or dangerous one. Tan and Begy work through mechanics, abstraction, and communication as the design levers that keep these games engaging while avoiding physical or emotional harm to players. Running 86 minutes, the session fits within a broader semester of game design lectures and treats live action formats as a distinct design problem rather than a variation on digital or tabletop games, with attention to how rules get communicated in real time to people moving through physical space.
