To me that should be pretty much "This general environment should have been prettier but how it is didn't really contrast from the story or gameplay." A game that's very nearly perfect but misses it because of something that is trivial - one that doesn't take away from the overall experience but is still there.
And what Metacritic did by scoring this game so high was saying that it's the best game made ever. And I'd argue that that's bs.
CS/CpE. Yay engineering!
