So i've put it off for years, but always knew the time would come for me to learn about Pathfinder. And since Pf2e has adorable, tiny versions of their books for half price, i'm thinking now is the time. I'm going with the BECMI red box intro dungeon, as it's first level and i have it more or less memorized. Core Rules and Advanced Player's Guide are the books i have access to, so they're a convenient limitation for Ancestries, Backgrounds, Classes, and whatever else. It's also bound to be pretty bare-bones, as far as presentation. So no complex API's just for flash, and no super detailed, photo-realistic dungeon maps. Just a backstory for why you're at the dungeon, and then you're at the gates. (likely with the sfx or music setting the tone.) If that sounds interesting enough to spend a few hours with, then check it out here.
