I'm going to do it. I'm going to remix Golarion. I've already got a good start with some earlier noodling that I did, but I'm going to actually start with remixing the rules. I'm going to use the Race Builder rules to build the races that Old Night has, I'm going to tweak available classes, use E6, and otherwise tweak the Pathfinder 1e rules to work for my setting, if I wanted to use them, and then I'm going to take this House Rule document and remix the setting. Some of the elements of Golarion will get a minor face lift. Some will be ignored and will essentially not exist for all intents and purposes (although I don't think I'll literally excise them, I'll just deliberately ignore them.) Where Golarion has nations that I'm not interested in at all, Golarion Remixed will have blank spots on the map with nothing of interest. Like I did with Eberron Remixed, changing up the races and adapting it to a low magic dark fantasy vibe will naturally change the setting quite a bit, and Golarion Remixed will work perfectly well with the Shadow of Old Night rules... but it won't need to, because my Pathfinder 1e House Rules document will perfectly model the setting as well. They'll be two complementary systems for achieving the same thing, and the "DesdichadoFinder" house rules for Pathfinder 1e will also work perfectly for the Old Night setting too.
But as with the Eberron Remixed project, the real fun is actually remixing the setting to fit the rules, including the allowed races and the changed assumptions about magic availability and PC power in general. If Darkness In the Hill Country is meant to be run in the Old Night setting with the Old Night rules, it could equally well be run in Golarion Remixed's version of Varisia with the Pathfinder house rules. That is, in fact, exactly the point.
There may be some third party rules in play. I'll almost certainly use the Freebooter class from the Freeport book, because it's a great class, and I like it for the swashbuckler archetype more than I like Paizo's own Swashbuckler class. I may also take some of the Madness rules from that book as well. (After I compare them to whatever Horror Adventures has, and even maybe what the 5e SPCM book has to see which gives me the best experience. This will be an old-fashioned "binder of house rules". Well, maybe not that bad. I hope actually that by kitbashing and mostly by limiting what's available, I can do it in just a few short pages. But it's a weird exercise. This isn't the way most people would play a Pathfinder game. But I'm not trying to play a Pathfinder game, I'm trying to get Pathfinder to accommodate my specific tastes for a low magic, dark fantasy game with a low magic, sword & sorcery, dark fantasy tone and themes. Although 1e is arguably a little better at that than 2e or than D&D 5e is, it's still very much a game of Open Society, Diversity, Inc. super-heroes who are meant to appeal to the power fantasies of broken wokesters first and foremost, so it'll need some help to get there. But it's not a lost cause; the elements are there, you just need to go through them with a highlighter saying "don't use this, it won't work". And that's 95% of what I'll be doing; creativity by limit rather than actually building all that much that's new.
Of course, although I'm pretty familiar with Pathfinder 1e from years of poking around it's PSRD and reading all kinds of setting and adventure supplements that are supported by it, I've never actually read the rulebooks in a the traditional sense. So this will also probably be a long-running work in progress, as Pathfinder 1e is infamous for, among other things, having lots of lots of rules spread over lots and lots of books. I've had many of the original core rulebooks in pdf for a long time; they were worth it to extract the art alone! but I've recently bought the pocket (trade paperback, really) sized core rulebook, and intend to start reading it shortly, cover to cover. But it'll be until I get to the Advanced Player's Guide and some of the other subsequent books that I'll really be able to start sifting through many of the options like archetypes and alternate classes, etc.
I've created a new tag, PATHFINDER REMIXED and a new banner both. Some posts will merit both Golarion Remixed and Pathfinder Remixed, but many will focus on just the rules or just the setting, and therefore will get one or the other.
