So, when I write a first draft of a game I actually make a pretty conscious effort to make sure it's written in a way that I think others could play it even from my initial alpha draft.
This has paid off exactly once when some people in Hungry played the very first version of The Extraordinarily Horrible Children of Raven's Hollow. If you would like to make lightning strike twice all playable drafts of my work can be found here: https://bloodthornpress.com/
I am working on making a few projects polished and published likely via POD channels but, man, production is hard.
