@ludovic Props for Ye Olde 18th century spelling of "musketeer"! (I googled, it's a legit archaic form of the word.)
When I hear "metaplot", I hear "The setting we sold you last year has now changed; King Goodguy is dead, Baron von Evilstein is on the throne, the city of Clicheopolis has been destroyed by a meteorite, and a spell gone wrong has given elves beards and made dwarves hairless all over. Yes, even there, perv. And if you want to use any of our next batch of supplements, you need to incorporate these changes."
I'm sure you see why this was met negatively. Your description is much more central to the individual game. It's one thing if *I* decide to nuke Clicheopolis. I don't have the publisher trying to control the flow of my campaign or undoing any foreshadowing or planning I might have done. #ttrpg #metaplot
