To sort of answer some questions about Zeus vs Thor, Odin, Baldur
I find this funny because it answers a few questions. I'm not all that interested in the Greek Gods versus Norse Gods debate, because if you think one pantheon is stronger than the other then you're just biased. You're either a Greek saga only fan or a Norse saga only fan.
But people always use Bruno, and only Bruno, to nerf God of War, even though he constantly keeps telling us that he is just an animator and not a part of the creative team and that lore is better sourced by concept artists, writers, and narrative directors.
The reason I add concept artist is because according to multiple developers like, Stig Asmussen, Eric Williams, and Cory Barlog, concept artists have pretty much all the say over lore, specific to things the artist creates. This is how we know the greek underworld is infinite. Because Cecil Kim said so and Cory Barlog backed him up.
