Larp stands for Live Action Role Play. That's about as simple as it gets when trying to understand what Larps are. They can be fantastical and magical, or they can be hyper-realistic dramas grappling with topical issues. And Larps are getting more popular -- maybe even on the verge of becoming mainstream. Game masters and Larpwrights Lizzie Stark, Evan Torner, Caroline Murphy and Eirik Fatland explain why playing pretend is the right cathartic outlet for our times, and how Larps are becoming a new kind of art.
