But in any event, are you able to explain how the bolded bit is different, in its fundamentals, from a PbtA GM asking questions and building on the answers?
I don’t play PbtA (not really interested in it from what I have read) so I can’t. What I can say is this is fairly informal and dependent on the individual group. I find most groups have differing tastes here. It isn’t like the formal mechanisms you have in hillfolk for example (not sure if asking questions building answers is a formal mechanism).
