But how are those details, of where the PC learned things, established. And how do you create the character's memories? Does the player decide what the PC remembers about religious matters? Or does the GM? If the latter, is this a departure from the principle that "The GM controls the world, the player controls the PC"?I don't think your description of knowledge checks is accurate. When I wrote down 'proficiency: religion' on my character sheet, that already establishes my character is knowledgeable about religious matters. The check doesn't establish specific other details about the past--i.e., 'in year 3 at university, professor Ramsey gave a lecture about...'.
And so why does the Apocalypse World human ears example count as a departure from "the GM controls the world"? Or the strange runes example?These are well within the purview of the DM. We don't need to accept "my PC dodges every attack and hits the enemies in vital areas with every attack" to say "the player controls the PC".
If "control" is not being used literally in one case, why must it be used literally in the other case?
Not obvious at all, because I don't know what either bit of jargon means. I don't see how having things hinge on a GM decision in response to a wandering monster check is different from having it hinge on a GM decision in response to a player's roll is different from having it hinge on a GM's decision in response to a player's question, as far as "quantum" goes.I flipped the order accidentally. The claim from before was quantum for the GM but not the players. (I should think this was obvious...)
I mean, if you wanted to say that the GM's roll for wandering monsters is different from the other two, because no player is involved, OK.
Or if you wanted to say that the roll for wandering monsters and the skill check are different from the third example, because the latter is an extrapolative decision with no roll involved, OK.
But I don't know what it is that you are saying is supposed to make the first and third "not quantum" (for the GM and/or player) whereas the second one is.
