Letter Writing TTRPGs
A letter writing or epistolary TTRPG uses letters between players as its medium. Many of them are like guided writing exercises, with prompts to help guide what events occur for you to write a letter about—but of course, the letter you receive influences the story just as much! These are two-player games (usually), without a GM or a single person controlling the narrative. Instead, players respond to each other's actions and writing, with game mechanics influencing what happens for you to act upon.
Some letter writing games are more mechanically driven, but I prefer to enjoy games that are a little mechanics-y and a lot prompts-y, so keep that in mind as you look through my recommendations! If you have a pal to play with, letter-writing games can be a ton of fun (and if you don't, maybe hit me up).
My Recommendations
I tend to enjoy games with loose rules and not a lot of tracking or mathematical crunch. Please keep that in mind as you peruse!
