By all I've seem, PbtA sounds like a system that is not focused or workable for a family-friendly PoV, unlike Fate, that have some good family-friendly settings, like Do, Young Centurions and Strays. The more "family-friendly" setting I saw was The Warren, and they give too much space for brutality, including the pregnancy (not because the pregnancy per se, but because a rabbit mother can Panic while giving birth). There's any hacks for PbtA that could go into a more light-hearted, family-friendly setting, like the ones I've cited from Fate?
I'm saying this because I'm working into a Fate setting with a vibe like Get Along Gang and Jakers! The Adventures of Piggley Winks, and I'm thinking on working the same setting as a PbtA hack, and I want to see some ideas.
