Why go to the castle from the caves for A and B? Maybe they got a taste for exploring, heard some rumors while cashing in some artifacts from the caves, and decided to follow up on them. How are we not looking at a campaign here? You've got DM, player, PC, setting, and time continuity linking the adventure sites together. What you're missing, compared to an Adventure Path, is a DM/Author-organized story. So are you saying that's necessary for a game to be considered a "campaign"?
So, we're in agreement then. To have a campaign, you need some sort of causal linkage between adventures. That causal link doesn't have to come from the DM (I never stated that it did, quite the opposite in fact) but there must be some sort of chain of causality from one point to the next and so on.
That chain of causality is entirely lacking in your stated example.
IF there is a reason why the group has split up five times in five adventures, and IF there are causal links between each adventure, then YES you have a campaign.
OTOH, if the only reason A is going to the castle is because that's the adventure the DM had prepped that night, then no, you don't have a campaign, you have a series of one offs.
But, isn't it interesting Bill91, that your definition of a campaign didn't require any reference to a setting. In your definition, setting is completely irrelavent to whether something is a campaign or not.
The relavent fact is whether or not there is a "time continuity" linking the adventure sites together - which I take to mean a causal chain. (please correct me if I'm wrong)
So, no, you don't need a DM imposed story for a campaign. I never said that. Nor will I ever say that. You most certainly don't need that. I would never claim that sandbox campaigns are not campaigns. In the same way I would hope that you would never claim that an adventure path campaign is not a campaign. They are both campaigns in exactly the same way - a chain of events where you can follow along point by point and understand exactly how you got from A to B to C.
But, nowhere in that definition do I require anything about a setting.
So, how exactly does setting=campaign?
