Lego escape room. All four of the players were old hands at escape rooms, and I am apparently not; they were figuring out this stuff a lot faster than I would have, so I didn’t have to bother with feeding them hints and stuff. I *believe* that they all had a good time; I did, although it wasn’t the good time that I was expecting. I was expecting to have them chisel through walls and stuff and kill monsters and suchlike, but they didn’t seem into that and one of the GM’s jobs is to not get in the way of other people’s fun.
Besides, if I do it again next year I WILL run a Lego Dungeon; and that will be the body-horror surreal run of my fever-dreams. This, I swear.
