OK, let's see if I can draw up a few hypothetical game histories here and see what's a campaign and what isn't...Nonlethal Force said:I view a campaign as the "tales of a certain set of adventurers." Granted one or two may come or go without calling it a new campaign. But if the characters change too drastically with different goals and motivations in my book that is a new campaign.

Terms used: "Single-track" means one party all the way. "Two-track" means two (or more) parties in the same setting with little or no interaction. "Multi-track" means two or more parties regularly interacting. Anything other than single-track assumes the parties are being run concurrently i.e. there is more than one session a week (or whenever).
I'm assuming no major mid-stream rule changes...rules used at start are rules used at end. Which of these are campaigns?
Game 1. Same DM throughout. Single-track. One adventure only. Characters A,B,C,D start ==> characters A,B,C,D finish.
Game 2: Same DM throughout. Single-track. Multiple adventures tied together by a single story arc. Characters A,B,C,D start ==> characters A,B,C,D finish.
Game 3: Same DM throughout. Single-track. Multiple adventures that start and finish more than one story arc one after another. Character turnover not related to story changes. Characters A,B,C,D start ==> characters C,D die off and are replaced by E,F,G ==> characters B,F retire and are replaced by H,I ==> characters E dies and is replaced by J ==> characters A,J die ==> character B comes back in ==> characters B,F die and are replaced by K,L,M ==> characters G,H,I,K,L,M finish. (player turnover almost as great as character turnover, but at least one makes it all the way through)
Game 4: Same DM throughout. Single-track to start, splits into two-track later. In most other respects same as Game 3 along each track once split. Little to no character crossover between the two tracks. Complete character turnover between start and finish overall and on one of the split tracks; the other split track has at least one character survive throughout. (this was my Telenet)
Game 5: Same DM throughout except as noted. Single-track to start, splits into multi-track later. Character turnover similar to Game 3 except also lots of character crossover between parties once multi-track starts. One party jumps to another DM's world for one adventure then returns and continues original game. Several embedded story arcs started and finished at various times by various parties; sometimes a story started by one party is finished by another, knowingly or not. (another DM's Dafan and my Riveria was/is like this)
To me, 2-5 are each campaigns, though if someone says that Game 4 was one campaign that became two I'd not argue too long.
