Sage LaTorra said in the thread on whether DW is suited from a gritty & low fantasy campaign that you should judge the “Judge the fictional situation, not the narrative worth” as to a lowly NPC killing a PC with a single blow.
I would like to ponder a moment on this sentence (hence I am creating a new thread) and put it in a wider context.
I think it is an interesting sentence because it pits fiction against narration but I am afraid I respectfully disagree.
I actually think the exact opposite which is that at DW, Narration trumps Fiction by miles.
My understanding of DW rule system is that it was not created to simulate a fictional world but rather to tell an interesting story.
Do not get me wrong: I think that the GM should take great pains not to disrupt the suspension of disbelief around his/her table.
Once this is said, the GM should however not think in terms of plausible outcomes (hence there is no difficulty modifier at DW regardless of the task at hand) but rather in terms of interesting outcomes.
Hence, screw the fictional situation if it allows you to tell a good story instead.
