This game has a great ambient atmosphere to it which I really like, but, what seems unrealistic is the wind physics. For example: The trees sway too much, bend too much. The grass also sways a bit unrealistically, shame the atmosphere is spot on. This seems a bit distracting and I think they went a bit over the top in this one. Watch the Youtube videos recently and you will understand my point. This is just my opinion on it.
Don't agree.
You see one area of the game that's windy, and you assume that the entire game is going to be as windy, at all times? ;p
