Remathilis
Legend
Bits and bobs. Mercer's gunslinger and blood hunter. Zarieth's witch class. Stuff found online via DMs Guild and GM Binder. I've considered Grim Hollow and Primeval Thule as settings, but haven't run them yet. Run a few Goodman modules.
But no, I haven't really used 3pp in any serious capacity since moving from Pathfinder. We've briefly toyed with other 3pp games (Starfinder and M&M) but neither seemed to land fit us. For the most part, I was happy to occasionally augment my D&D with some new options, or try a d20 based game in a different genre, but I mostly stuck to WotC's offerings.
