Yes, all of it falls apart with GOW Ascension existing, all creation myths being valid and coexisting with each other, Asgard having a massive mountainous landscape even behind the "edge", Kratos being unable to physically go back without Unity Stone which "cuts distance" which is blatant hax, Greek World tweet further shoots it in the foot with the Pantheons being separate, literally hammered multiple times that Pantheons are separated by geographical divides, Interpantheon bullshit still doesn't happen, bullshit from other Pantheons like Gaia breathing in continents and Sisters of Fate sinking continents doesn't happen in other pantheons, Vanaheim day-night cycle change or the timestop bullshit does not affect other realms, Realm Shift BS that confirms the Realms to be separate space-time continuums, multiple Underworlds are not in conflict with each other, Poseidon is the god of all seas which would come into conflict with Njord but it doesn't, the whole "Same Earth" tweets are blatantly in reference to the "greater universe" that Cory talked about where all the pantheons coexist and have control over their own universes.
It's almost as if being on the same "Earth" doesn't tell anything about that "Earth's" true size given the above. Just ask Elder Scrolls, DC, FATE and a couple more to go around.
