Ok i played it now for about 5 hours or so.
I like how this game starts and for me, those world war scenarios are very emotional. 
Artwork is great, running on mid on my old system, without lag.
I was very confused, how quick you get a bunch of good weapons.( to easy)
All this crafting stuff is to much for me, do not like it, get bored quick.
Dialogues to long for me.
It feels more of a brutal genre mix, then fallout feeling.
It is a cool game, but i personal do not like it. Last fallout part for me.
For someone who starts with 4, sure it is a great game, feels like bioshock in some areas.
But i started with part one and i really liked it.
