Continuing the discussion from How to write a series bible:
Item twelve on the checklist is Season Finale.
12 Season finale . If you have designed a serialized show, or even if your episodic series contains serialized elements that carry over from one episode to the next, then you should end with a short description of how your series ending its first season. Will the main conflict be resolved? Or will there be a cliff-hanger that carries over into (hopefully) Season Two?
Here I think we may confront an item that is definitely important to a TV series and usually not applicable to an RPG campaign. In the case of what I used to call a “miniseries campaign” and @RogerBW pines for by the name of a “telenovella”, then even though you might have no way of telling what the course of the plot is going to be, the nature of the core conflict is such that eventually the protagonists and their antagonists must meet at some inevitable Philippi. But I don’t think that even all miniseries campaign need a decision a priori of what the crisis will be, let alone its resolution. And besides, a great many RPG campaigns are intended without a through plot with a sustained core conflict susceptible to a final resolution — like TV series they are intended to keep going until the ratings fall. But unlike such TV series they aren’t usually planned or executed in seasons.
Note that Ury is indicating the need of a season one finale in every series bible, not any need of a series finale. I can’t think that that applies to RPG campaigns. Though — my campaigns when I was at university did have a tendency not to resume after the long holidays, even when they had been apparently puddling along perfectly fine until exams. Perhaps there is something to do when a campaign has to go into hiatus to improve its chances of getting resumed.
