I was playing in a long-running FantasyCraft tabletop campaign before lockdown put it on hiatus.
Overall, I have a positive impression of the system. I'm not a huge fan of D20 but the Crafty systems generally let me get what I want done as a player.
My character is a kung-fu doctor, patterned after Peter Davison Doctor Who, built as Explorer class with the Cleric specialty and a combination of martial arts, chance and alchemy feats. It all works pretty well. My only real issue is that combat and damage are a bit too random. My character has both one-shotted a Big Bad when my damage rolls exploded, and gotten his ass kicked and his lunch money stolen by a nameless villager. But that's D20 for you.
We were using FantasyCraft with a Pathfinder campaign, and it worked pretty well.
