Pemerton. These were my questions (and they were asked sincerely: they weren't a trap or anything).
And this was your response:
I genuinely don't understand this answer
Your question doesn't make any sense.
It's like asking, how much does the whiskey shape the taste, if the cook has decided to make pikelets?
I mean, I'm sure in the history of the world someone has made pikelets using whiskey, but on the face of it the question I've just stated is a non-sequitur.
To repeat, here is the core relevant rule of BW, from the GM's side:
"The GM is responsible for challenging the players. . . . The GM presents the players with problems based on the players' priorities" (Gold Revised. pp 10-11)
So when you ask a question that, to me, seems to be *Can the GM nevertheless ignore those priorities and just play a prep-driven game?" it makes no sense to me. What are you trying to find out?
And when you ask about
the prep of concrete details ("would it be okay for the GM to have such a concrete detail") my answer, like
@Campbell's, is: it depends. Tell me how those concrete details actually relate to what the GM is tasked to do by the game, and I will tell you whether or not it is appropriate prep.
Similarly, in this thread,
@EzekielRaiden and I had a back-and-forth about what sort of prep fits with Dungeon World's principles of play.
