I recently came across this website: https://letterlarp.home.blog/ which really intrigued me.
I’ve played in a failed game of De Profundis and I think I know some of the reasons it failed, players mis-estimating their available time for long-form letter writing and early letters getting lost in the post that killed the momentum.
But a letter larp remains my great white whale. I’d love to know what ideas everyone has on how to make something like this a success - in terms of player momentum, asynchronus play and all that stuff. There is a section on the site I linked to about running such things but I don’t think it really digs into a lot of the reasons why such games fail.
I definitely think having a prompt of some kind makes letter generation easier and also helps reinforce the themes you want showing up in play. You could even do multiple prompt lists for tone, event, etc. or different prompt lists for each character.
