After 12 years' worth plus a spate of requests this past weekend, I'm doing the unthinkable and/or unconscionable and writing up an Apocalypse World SRD.
It's going incredibly well. I can't even tell you. It's a mean, stripped down version of my PbtA articles, laser focused on making a cinematic ensemble action-drama-thriller game like AW.
I don't know how many games it'll inspire, of course, when it comes to it, but it's a tight piece of practical RPG theory anyway. I'm excited to share it.
@lumpley I just spent 5 or 6 hours googling the internet for exactly that! Thank You.
