and now dealing with the Elephant in the room, The GoWII Time Loop.
I see people saying that Kratos going back in time created another timeline, but that isn't true!
In Atlas flashback we see the titans get transported to the present.
This means that the time travel happens withing a single timeline.
I also saw some theories saying that GoWII and III happens at the same time, but this is also not true, as Kratos brings the titans to the PRESENT, not after the fight with Zeus, this means that still all the events from GoWII happened, only the POV of the fight is different, from Kratos' POV GoWIII happens soon after the fight, from Zeus' POV it happens some days after it, enough time to destroy Sparta for search a marked warrior that almost killed him, also pointing out that Zeus doesnn't have the Blade of Olympus when he destroys Sparta, nor the weapons appears at all after the intro of the game (aside the flashbacks and the final fight that takes place during the intro).
there's only 1 issue, the Athena staute cos if what i say it's true, then Athena should be already dead, tho since in GoWIII she returns as a ghost, she probably told him to not trust Gaia, cos she wanted to manipulate him for her own plans, as she did in GoWIII after Gaia betrays Kratos, and she did it as a Statue even tho he was a God, so he should not be hidden from seeing another god, for not creating a time paradox on her death, as it made her plans simpler.
That's my conclusion, if you find smt that doesn't make sense just tell me. That's the best I could have come to.
The only thing that could destroy everything is the GoWII novel, as it has a subplot about Hermes on Olympus. (Yeah both the 1st and 2nd game novels have extra scenes with Gods talking about Olympus).
