Yeah it's a bit of a turn off for me.
It's like Uncharted 4 getting rid of all the over the top action sequences in favor of the better story and character development. I loved those aspects, but the game still ended up being me second to least favorite UC. I want to be in collapsing skyscrapers, derailing trains, and crashing airplanes. Not exploring huge empty maps.
At least Kratos and his son may be able to carry the story like Joel and Ellie though. The problem with UC going that route is that the characters were never really all that three dimensional with the exception of Sully. Drake himself was always kind of one note especially. Kratos was too in prior games. This game looks like it will flesh out Kratos a ton.
