If that is true (including theories like Schrodinger's Cat Theories, MT, Quila Space, etc) and some concept of Philosofy, religious and schools..., this will be a huge upgrade for the verse at some point.
I hope that some places or "spaces" like The Expanse are "bad translated" and are beyond Space-Time (not only Past Present and Future), because is the realm/home of the mayority of demons and also in his true form/nature before Human comprension and observation changes his apareance and nature (i believe that some if not a lot of demons outside The Expanse are manifestation of the true self, avatars/fragments or they are limited).
Also, a lot of games have difurcations/separations but still coexist in the same Cosmos, that separation start between SMT1 and 2 (Like If the precursor of Persona, Image, Seven, DeSu series, etc) and not to mention that Raidou games can changes timelines/continuities directly or indirectly an alter MT games (one posibility in 3 is Dante, another is Raidou and are separate timelines/coexistences). This also may be proof that MT Games not only are a hell of continuities (better tha zelda :v), but also that many theories, concepts coexist at the same time, mani time lines, universes, variations, posibilities, etc coexist in the same Cosmos at the same time, shared or not.
Also there are variations of the same game with not only ALL ENDINGS are canons but also all games (Vainiya, Final Product etc) are canon and a variant of the same Universe or cosmos like SMT3, Strange Journey/Redux, SMT4 and Final (Final remember is a What if of SMT4 nad this is canon and a mayor plot for any game in MT franchise).
Also I believe that in any game, a mayor antagonist (Fake, or True one) is an avatar or a sensor of YHVH in one or some way as he limited almost any being in the series and beliefe that he is the greats one and the true one.
Well, this is my opinion. Also i want the SMT5 for PC, not the ******* Nintendo Switch e.e and my school of filosophy, religious and metafisical concept in the Jewish Mysticism like the Kabalah,Ein Soph, sephirot, Qliphoth, etc
