I don’t even remember you mentioning Torchbearer, but I’m super interested in it and loathe to work it out for myself, so chalk me up as up for that too.
I would give running (or playing) Epy a shot. Like I said, ask me after I run two games this weekend (is it weird I have more anxiety about putting it on the group’s table instead of just rolling games at cons?)
Epyllion is simple, but runs off of / teaches you / forces you to refine three skills. Two are normal PBTA – Managing spotlight and asking questions. Aside from a one-page rundown of ideas, basically everything about Dragonia is player question emergent, and your GM job is basically to set up the scenes that make playbook moves trigger, done. Because Epy is otherwise kinda simple, I felt like it gave me time to focus on an do those things.
Thing 3 is being adorable and generating cute things, but I already had that so it was an easy lift. I’m not totally sure how to recommend building on this without a table to bounce ideas off of until everyone laughs.
If you’re in Hans Messersmith’s boat, I think it’s a mix of two things – Making friendship-themed/challenging plots, and making stuff draconic. The first is easy – Just have the Hazard section in front of you, watch the first act of a My Little Pony episode, and practice translating the conflicts to the Hazard types. The second is a weird lateral thinking exercise, but luckily the table can help with that. (Dragons spill too much trying to hold goblets in claws, so how is everyone at your nestmate’s first-flight party drinking their banana-wine?)
