Hi, I'm from /aicg/, I am that guy who uses some simple prompt magic and lots of autism to adapt tabletops I'll never get to try IRL to SillyTavern frontend. Sometimes it's sloppy, but mechanically it works great. Free roam is shit, but adaptations of adventure models work almost flawlessly.
Anyway, I was thinking about adapting Pathfinder 1, 2 or 3.5 next. What's the best choice? I can make a compatibility layer between 3.5 and PF1e.
Pathfinder 1e + Starfinder 1e are the right choice, aren't they? They have the most adventures and supplements.
