Really? You never write an adventure? A scenario based on the likely actions your players will take? Never run a module? All of those things look surprisingly like chapters.
A non-scripted scenario can never be based entirely on likely actions the PC's might take. I have to base plans of action
for NPC's based on what they know. Depending on the situation the outlined scenario might feature
the NPC's anticipating and setting up counters for specific types of interference to being completely ignorant of the PC's at all. I am using a module in my current game [2E Return to the Keep on the
Borderlands converted to 4e]. The scenario outlines actions that NPC's plan to take and how these actions may differ if the PC's become involved.
Deliberately misinterpreting the definition of a word is not helpful. Again, unless every encounter you run is nothing but ad libbed random encounters, you have to design in scenes. Have you ever keyed a map? Then you have scenes.
It was not a misinterpretation, it was one possible definition. How does keying a map= writing a scene? If I say that Area 5 on the map is the lair of a hungry owlbear, what makes that fact alone a scene? Area 5 only becomes a scene or setting if the players interact with it. The players may give area 5 the old right hand wave and never explore it.
Area 5 contains what it contains. It is not random.
Do your NPC's have no goals or timelines? Unless everything in your world is absolutely static until such time as the PC's interact with it, then you have story arcs. Baron Von Badass is attempting to seize the crown is a story arc whether you like it or not.
Yes. NPC's have goals, tactics and resources used to acheive these goals, and sometimes these goals are time sensitive. A plot and a
timeline do not equal a story arc. The missing component is the players and their actions. Baron Von Badass attempting to seize
the throne is a plot being hatched by the Baron. A story arc by definition spans something and assumes activity and involvement by the PC's.
The purpose of a story arc is to move characters from one state to another. If the players are responsible for that movement then it cannot
be written into a pre-defined arc.
If you have plots, and characters, then you have stories. That's all it takes. You have every element a story needs - character, plot, setting. Trying to claim that your game has none of these things is pretty self-contradictory.
The end product of play does not have to equal the purpose of it.
Wait... so, your game isn't run in sessions? Do you have some kind of continuous gaming paradigm going on? Play by post or something?
It certainly is. Does a game session have to equal a chapter? Last session we ended in the middle of tense action during a brief pause. Next session we will pick up right there.
That seems like a needlessly pedantic nitpick. If you don't have scenes, then nothing actually happens in your game. Or; there's no pacing control. Everything happens in realtime. You never fast-forward to the exciting stuff. A random encouner in the wilderness would be, for instance, a "scene." Without scenes, you have to play out the entire journey. Every step of the way.
I don't think you really mean that there's no scenes. I think you're distorting the meaning of the word beyond common usage to advance some kind of pro-sandbox agenda.
Of course games have scenes. Of course they have sessions (which may or may not resemble chapters or episodes to some degree or another.) Even the most sandboxish game I can possibly imagine would be impossible to run otherwise.
Given the various definitions of scene, then yes in the sense of a locale.
That doesn't make them "not story arcs."
A story arc has a targeted end point. The DM cannot predict or write the players part and the players cannot predict or write the DM's part. The whole point of a story arc is to map the flow of the story to it's desired conclusion. A game does not have a known desired conclusion and thus the arc has no endpoint. This is a device useful for
fiction, not gameplay.
