What I found most controversial before start was that the game was already sequenced into "chapters" (a broader concept of "scenes"). Quite open, but with prompts like: "First meeting. Focal character survives" and even "Focal character dies". But where the scene is set, and how it's played out, is totally up to the players in the moment.
It worked, it really did. It was like being handed prompts in an improvised theatre session, with a shared context and clear boundaries.
