Never say never, but:
- It would be a ton of work, I'd have to relisten to every episode for any given setting, take a ton of notes, etc. And you know, I have a pretty tiring full time job as it is (on top of FatT, AMCA,and Shelved by Genre (and trying to be a good friend, partner, and son)).
- I've lost some of the prep I've done over the yeras, and that prep is often in shorthand or reference, so it's not like I could just easily transfer material over anyway.
- A lot of big rules/ideas for any given setting live in my head while we're running, and many of those have been lost to time. I haven't
- There isn't really a huge audience for it. FatT has an incredible, die hard fan base, but it isn't huge, and that might make it a hard pitch to a publisher.
- I'm not thrilled with the idea of game-agnostic setting books. The thing I love about games in general and TTRPG's specifically is the way systems and narrative blend and inform each other. Releasing a book and saying "Here's Hieron" or "Here's the Divine Principality" would, in some ways, be lying. For me, they exist at their best inside of a ludic context that brings something new out of them.
- Most importantly: A lot of our seasons not only allow for but leverage ambiguity. We've talked about this in post-mortems over the years: There's a certain sort of question about our world that we don't want to answer. We like the blank spaces, and my instinct in narrative is to resist the reduction to the catalogue.
In some ways, Realis could be an exception to this. Would love to have that published once it's finished. But, it's also not a setting sourcebook, it's a (flavorful) set of rules that includes a broad setting and some sample locations, but that's it. The joy in it--as folks will see sooner than later--is partly in building their own setting inside of the premise of the game.
