Assuming you are using one or more published adventures as the GM of a campaign, are you "required" (by courtesy, if nothing else) to tell your players a) that you are doing so, and/or b) what published adventure you are using.
Now, in the case of something like The Enemy Within for WFRP, or Curse of Strahd for D&D 5E, or any other campaign length published scenario, it seems to be me to be built into the pitch in the first place. "Do you guys want to play The Dracula Dossier?"
But, with a more sandbox campaign that uses adventures to fill it out, the question gets murkier. It feels like the GM probably should give some indication of the fact that they will be using published material in the campaign, but I don't feel like there is any need to say when that is happening or which ones. That castle on yonder hill might be the result of the GM's imagination, a series of random tables, or a published adventure location. Does it matter?
What do you think. When must a GM say that they are using published adventures in (or even as the basis of) the campaign? Are there tangible consequences of doing so or hiding the fact? Do you usually tell your players if you are using published material?
