I’m having the same problem. There’s some discussion on MeWe, but little of it 13G (and I only got 13A for 13G, but it looks like a fun system).
We did character creation together and, man, that was a slog. I began questioning whether RQ or HQ wouldn’t have been easier (systems I’m more familiar with, but the group balks at). I wish they had put all the class info in the book at least. Passing all those books around was a bummer.
