I will also “bite” with a my attempt at a philosophical answer to OP
Short answer: No
Why?
?What is a game?
!Disproved Plato’s Pure Forms!
(and over 2 millenia of western philosophical thinking based on that crap (essential to most dualism), that even many of P’s students wisely wouldn’t buy, back in the day)
Is a game… Collaborative or Competative Fun or serious Rules absolute or negotiable Etc etc
While this is an extreme case, its a problem for some aspects of many/most/all relevant observational schemas
Clearly there is no “ideal” game definition, and thus can never be an “absolute” agreement as to what is or isn’t ABSOLUTELY a game.
However, for a given sub-culture (of similar biological and experienced beings) there can indeed be quite extensive agreement, and only a few debates, as to what is a game.
So, for now, I will take this position to OPs OQ.
That we will not be finding an objective reality, that any such schema will have problems, but in as much as there is close alignment of observers, there indeed tends to be sufficient agreement regarding many things, that a subjective experience imperfectly becomes a shared reality.




Thanks for clearing me up. Ok that’s interesting. And does very much speak to OP
I can immediately grasp a major support of the position, in that principia mathematica are self - evident/supporting/emerging (ie axioms and theorums), so yeah thats pretty strong reality.
But…
Im a way, doesn’t the nature of a “pure mathematics reality” indeed sit apart from “our” reality, like (how) can it exist (in some way) without a world?
So IS that strong support for a type of dualism?
Is the old joke “God exists and he is a mathematician” valid in that respect?
