Another unsubstantiated and overly used statement. I have never played call of duty and am not a fan of the fallout 4 graphics. When compared to most games now releasing it is years behind visually. This is not an opinion it is fact. It is opinion that some people like the art style or visuals and think they are fine or don't like them.
You can't argue if you put an HD stream of Fallout 4 beside most modern games.
Have you seen the running and dialouge animations? They are very far behind the current standards in gaming.
