Interesting.
I've been a fan of God of War since the original, and I was pleasantly surprised at the new direction the series is taking. And I didn't even have franchise burn with the old direction. I could Blades of Chaos my way through Ancient Greece until the cows come home, but GoW 3 felt like a great conclusion to that part of Kratos' life.
I like that this new series is set in a different mythology, which I remember David Jade saying back in the day that his plan was to one day have Kratos wreaking havoc through all sorts of mythologies. I feel like this is a realization of that concept. Also, it's video games, so I just go with the flow, especially when God of War is involved. It seems like a lot of creative liberties are being taken with this new series, and the world is in a new age of gods and monsters. God of War was never an accurate portrayal of Greek history and fitting into a particular historical timeline in our real world history.
In the God of War universe, it seems like the age of Greek style gods is over, and the Norse style gods have grown from those legends of Kratos' exploits. The thing is, Kratos isn't dead, and has found himself a few millennia into this new age, where his exploits have been no doubt told and retold and shaped this new land. And now he has to live in it, with his son, and who knows where that's going to go?
Perhaps in another portion of the world, an Egyptian themed mythology has sprung forth, and in another part of the world, Ancient Japan, Ancient China, Mayan, etc etc. they aren't 100% accurate versions of the mythologies we know from our world, in the same way the original God of War games weren't accurate to Greek mythology, but it doesn't matter. GoW isn't taking place on our world, so the devs can have fun with it.
As a long time fan, I'm super stoked about the new game.
