Are there any role playing games explicitly designed for play-by-post? I know many games can be made to work that way. And I know there’s a variety of epistolary games where “play” is functionally independent but shared via letter.
I’m curious about actually interactive, collaborative RPGs with structural or mechanical support for play-by-post (where “post” may be email, forum, chat, etc). I’m extra curious about your personal experience with them, not just a link to an Itch or DriveThru page.
