i run ttrpg games *very* rarely, just halloween one-offs every couple of years. but! here is the the most fun theatrical trick i've played on my players. it totally got them
this was a story that was going to begin with the players playing themselves, sitting around the table in my living room, and then in-game the living room (and the players) would be transported to another plane
i rigged up a bluetooth speaker next to the window and closed the curtains. about ten minutes after they came in, before the game even began, i began playing rain sounds very quietly over the speaker. every couple of minutes i turned the rain up louder. just as the game began, with the rain at near maximum volume, one of the players even said "wow, it's really coming down out there, it wasn't even raining when we arrived"
i wrote a creepy verbal ritual the players had to complete as a group to transport the room to another world. right as they finished the ritual, i turned off the lights in the room using a remote and turned off the rain sounds at the same time
it was crazy effective. realistically it only took them a couple of seconds to figure out how I'd managed to turn off the rain, but they all said later on that those few seconds were completely disorientating, even frightening
anyway, i'm still proud of it 💜
