Previous inconclusive meta: How should the "story" and "plot" tags be used?
To me, there's a bit of a difference between them.
Plot is something that will, or at least, can happen. Your campaing have a plot - the planned events that you want to put the players in.
Story, on the other hand, is something that already happened or is more or less static: your character background, the lore regarding a magic item, the tales regarding the founding of a dungeon, that kind of stuff.
The "Plot" tag should be more about planning stuff, while the story tag would cover telling stuff.
At least, that is how I would use each tag. If this is the way they are being used, that's another matter.
For instance, this question asks for advice regarding how to handle what seens like railroading. This question end's with a interesting phrase, with the questioner seeing cleary that there is indeed a difference between story and plot.
Thinking a bit more about those tags, however, it seens that neither of them are really necessary.
Story would be about:
- Review of Stories - No good, RPG.SE is not for reviews.
- Creating Stories - No good, too opinion-based.
- Asking how to close a gap in a story - While narrower, still too opinio-based.
- Asking general methods about how to create a history - that's more like it, and the only use that I can devise to this tag.
Plot suffers similar problems:
- If it is about a missing element to your plot, like a monster, a special spell or a NPC, it would use that tag (monster, npc, spells).
- If it is about how to create a plot, that would be gm-techniques or campaing-development
- If it is asking a review about a plot, that would not be a good fit for RPG.SE.
- If it is asking about how to resolve player action inside a plot, that too would be too opinion-based to fit here.
So, while I can sey they are indeed different, I can't say they are useful.
No, we don't need them both, and we should make one a synonym of the other.
Multiple dictionaries define "plot" as primarily meaning "secret scheme", and secondarily meaning "story". We've been using plot in the second sense, which means we're using it exactly as a synonym of story. We can't get much more of a solid synonym than that.
Thales makes a distinction between them that plot is forward-looking narrative and story is backwards-looking narrative. The definitions we're operating on don't make such a distinction though, and netiher have the users — both tags are being used both ways.
If we want a tag for the first sense of 'plot', as in secret schemes, we should pick a clearer name for the tag like secret-scheming.
