The series has dealt with different pantheons since the second game (does a montheist religion like Christianity actually have a pantheon?) and it is all in the same universe. The game references previous entries regularly, and it is all very much connected.
Easter eggs. Different from showing the living, breathing Odin in God of War II. It's not right in my face.
I'm pretty sure I ripped many, many people clean in half in the new God of War.
The violence was tame. Sadistic violence was rooted in God of War's identity. It was entertaining.
Sex and nudity were not as prevelant in Norse culture as they were in Grecian cultures. It would make very little sense for the game to feature those things just because.
Assuming the Norse pantheon is the only candidate, I would have brought sex and nudity in anyway, because that was also a part of God of War's identity and it amused me. Adultery was common in Viking life and people didn't have as much privacy or clothes.
Your rebooted game doesn't sound much like a rebooted game, and more just a retread of the exact same things that the previous games did.
You think that because you have no imagination. Some tonal things DO need to carry over if this reboot is to pretend that it is part of the same series. If this really was a faithful sequel, they would have called it God of War IV.
Also, the camera I mentioned would have enhanced the combat and allowed platforming, so screw the zoomed over the shoulder cam.
