Watching a nifty video for the Roll20.net computer-moderated RPG system, I notice that the narrator uses “campaign” to refer to a single combat set-up: maps, counter placement, etc. For me, that’s not a campaign; it’s a scenario, or perhaps an adventure. As I learned it, a campaign must be a linked series of adventures or gaming sessions. But I’ve increasingly heard people use “campaign” to refer to a one-time instance of play.
This seems like a recent thing; I don’t remember people using ‘campaign’ that way before about a decade ago, at the earliest. What about you? Have you heard the term shifting?
