Campaign

A campaign is an ongoing storyline revolving about a continuous group of characters. It is generally made up of a series of adventures within a specific setting.

Since the word 'campaign' implies a series of military conquests, games wishing to distance themselves from such martial pursuits have alternate names for their campaigns. For example, Ars Magica campaigns are known as sagas and Vampire: The Masquerade campaigns are known as chronicles. Several games, attempting to invoke the serial dramas of television, have used the term series.
