I never used the word "fiction". I said "events in game".
Now, personally I have no problem using the perfectly serviceable word "fiction" to mean "the events that happen in the imaginary game world, like Strongdor the Barbarian issuing a mighty challenge to the Ice Drake afore cleaving it in twain" so as to distinguish them from the events that happen around the table, like Dave rolling really well on his Boast check and getting a +1 to damage.
But some OSR fatbeards shriek like autistic frogs when you do that, so I avoid the word. Clunky as the alternatives tend to be.
I know you used events, which is what I try to use.
The thing is, you also said "it's all made up", which is the argument that gets used to mean "it's all fiction" which then conflates "the events that happen in the fictional setting that players create while roleplaying" with "the story people are creating OOC as they utilize various OOC narrative control mechanics, conflict resolution, etc".
It's just the case of some using very loose definitions of "story", "fiction" etc, and others using more specific definitions.
The idea "it's all made-up therefore it's all fiction" is a rationale that frequently starts with the loose definition as foundation, then moves to the specific definition when we get to mechanics, usually when someone is about to argue that a certain mechanics is not OOC/storygamey/narrative/whathaveyou.
So "it's all made up" doesn't really help anything was my point.
