Ok, my ttrpg beggartok game players and creators - here is the conundrum. People keep asking if the library can run D&D programs but it's just not feasible - the demand is too high. I had a monthly program - 3 GMs, 21 people, filled up every month and it couldn't fit into the budget anymore. SO !

Not a TTRPGer, but GMless experiences seem more apt for boardgames. If you want something w/ more of a story, Betrayal House of the Hill. But w/ such high numbers, I think Roll & Writes would do well/be more economical. Railroad Ink or Cartographers can hold an ♾️ number. Just laminate sheets for it.

... I need a game that one lone librarian could GM (no skills) for a room of people. I've thought of doing a kind of "alone together" game where everyone is essentially playing a solo game and can talk to the other people at their table or not... but is there anything I am unaware of?
