Players sit or stand in circle. Each player gets a note with something they must include in their de-briefing. Then, in order, they start telling what they liked or didn't like about this LARP that's supposed to be just happened. Whatever a player says becomes true for everyone else. The last two players play the role of the organizers of the LARP.
It's a game inspired by nordic LARPs and I think it's by someone involved with jeepforms, but I'm not sure.
What's the name of this game?
