Was it a good course of direction?

No, the plot of the old games was that he was looking for revenge against the gods.
It's a sequel

I hated it.

Soft reboot. GoW 1-3 are still Canon but this is why it’s like a soft reboot

How many time passed since gow3?

yeah, i prefer the gameplay from the trilogy but changes are always welcome and i like the story a lot

because he killed his kid due to them

We still haven’t gotten a explanation how Kratos survived the hole in his chest and what athena is doing

Unknown

4, it knows that Kratos kill Athena and Zeus and has the scar form being stabbed in the stomach in the 2nd game

What happened in the history?
