@Manbearcat Yeah, that's pretty much the sliding scale I was envisioning. I think where this conversation gets sticky is that the a given premise and rules set can be all over that map. I think this is because volitional play/dramatic needs are much more a function of how the GM and players play, via explicit or implicit conventions and agreements than they are of a given rules set. Some rules sets obviously support the idea more than others, but that's not, IMO, the prime mover (not that you said it was). This plays back to @Ovinomancer 's concern above that was conflating agency with dramatic needs, which I'm actually not, I'm subsuming that idea into the idea of agency and of agency-first play. Both because I think that's where it lives, but also because I don't do the one without the other when I run games (YMMV of course). Just to be tranparent about how my personal experiences and style are impacting this discussion.
