I am currently replaying all the other ones. What a great fucking franchise. The first one even has a pretty tragic story, it's not narrated with a lot of talent but it's really compelling and Kratos' story is such an interesting one.
I'm a bit hyped but also concerned about this sequel. I know that after Ascension they HAD to completely change the gameplay and tone of the franchise, but this father/son thing seems very superficial from what we have seen so far. I did not enjoy TLOU and this seems very inspired by it.
But Santa Monica is an OUTSTANDING studio, and although I did not enjoy the marketing so far, I really think they will manage to suprise us the same way we were all surprised by the créativity of God of War 3 despite the fact that it absolutely could have been a huge disappointment.
