I got Ryuutama for Christmas and it seems really interesting! Much more D&D-y than I'm normally into, but I'm digging the Oregon Trail feel and the whimsy. I haven't gotten to play or anything yet. But in character creation I got frustrated at how non-self-contained things were, so I decided to prototype a PbtA-style-playbook-inspired character sheet. (As is my wont.)
(I feel when people think about Apocalypse World/PbtA they often focus on the dice and moves, but honestly I think the playbook encapsulation and the GM direction are crucial as well.)
Anyways, here's what I came up with. Of course, maybe when I actually play my thoughts will evolve, but I still feel like this works pretty well.
