I love scones!
Back in college a ran a D & D game with about 20-30 people. We did a thing where if you weren’t in the immediate party, you had to hang out in a back room.
It prevented information sharing and could make people paranoid.
But it was killer. People I didn’t know would join for a couple of nights because they heard it was huge (it was).
The consensus was it was kickass. “I’d never seen something like that before”.
It ruined me for traditional D&D.
