@Kennon I recently spent a lot of time reading and rereading Class Warfare for Dungeon World. I'm normally turned off by class systems, I find them creatively limiting, but this book breaks up classes into specialties that can be assembled into a "build your own class" system. I did the math and there's over 90,000 possible combinations. Not all are viable but still, that's a lot of creative space. https://www.drivethrurpg.com/product/137634/Class-Warfare
