While not Remathilis, I'll try answering this: it matters in the difference between saying "Welcome to FR, and here's what my players have done to it so far" and "Welcome to FR, here's what I did to it before we started". If the mess has been made by the players then at least the founding assumptions about FR were all true when the campaign started.But that can't be any point of significant difference, can it?
If I ask (say) [MENTION=7635]Remathilis[/MENTION] to join my FR game, and Waterdeep is blown up, what difference does it make to Remathilis whether I as GM blew it up off-screen or whether the players blew it up in some previous escapades? If the absence of Waterdeep is enough to make it misleading to describe my game as a FR game, then that seems to be the end of the matter, regardless of who was responsible for the authorship.
And for my own part, I wouldn't care either way.
But what do you do if you want to use these elements as plot secrets? Geoff, for example, looks just like Geoff; it's up to the players to discover during the run of play that it's in fact being run by werewolves (and maybe has been for ages).ProgBard said:Most tinkering with established settings is pretty easy to communicate, though. And that's true even if your changes are kinda gonzo. I can imagine sending a message to a prospective group that ran something like, "Hey, guys, we're going to be playing in Greyhawk with the following changes to canon: The Duchy of Geoff is run by werewolves; Wee Jas has been replaced by the Great Old One Nyarlathotep; and I'm swapping in Freeport for the Sea Barons. Everything else will be more or less as the most recent setting books have it, with any other minor differences worked out as we get to them. If any of that messes up a character concept you were married to, send me a note and maybe we can work something out."
And it's funny that you'd use the example of Nyalarthotep replacing another deity, as the campaign I'm playing in right now seems to have run into exactly this problem - Nyalarthotep has replaced a deity.
And in my own game a significant Elvish deity has been - if not replaced, then certainly bumped aside. This didn't become known until relatively recently; up till then anyone playing a Cleric to this deity was in fact getting their spells from elsewhere. There's no way in hell I'd ever put this in a pre-game summary!
