Overview
This Powered By The Apocalypse game is a good option if you want to play with non-rpg folks. Drawing heavily from the TV show "Murder She Wrote", you play as a granny in a sleepy town who solves murder mysteries. We created characters and solved the mystery in 1 or 2 shortish sessions of 2.5 hours each. I lacked confidence in running it, and could have done better. I'd happily play it again to try to brush up on my PbtA skillset.
In the first play through, the group solved the mystery and leaned into a supernatural explanation for a solution. The second group failed their Theorize roll and did not correctly solve the mystery.
