You can have any exact meaning for your definition of phrase you like, but this is mine.
Excellent. We can now get to the root of the problem.
There is an almost ubiquitous phenomenon within the world of video game players, which is a desperate insistence that their own definitions for categories of games are valid, because "to each their own". Now, attempt to apply this logic to pretty much anything else.
The definition of "fascism" is:
a political philosophy, movement, or regime (such as that of the Fascisti) that exalts nation and often race above the individual and that stands for a centralized autocratic government headed by a dictatorial leader, severe economic and social regimentation, and forcible suppression of opposition
If everyone had their own definition for the word "fascism", the word "fascism" would lose its purpose for existing, because no two people would agree on its meaning. Furthermore, it renders any discussion about fascism impossible, because no one would be able to agree on exactly what was being discussed. This thread is a flawless example of this kind of dissonance, and it eventually reaches a point at which mockery becomes the only logical path forward.
This game is not confined to a single instance.
According to you, that's exactly what Solo is - its own instance. And while we share a background simulation, it has no impact on my (or your) activities beyond numerical changes within the background simulation itself.
