Perhaps some of the complaints by some people regarding graphics could be about too much saturated colors that look off in a postatomic setting and make it too mich bright and colorfull like if all thigs were kinda new and not much used look or ruined?
I personally think that those bright reds and blues etc shoudl be tuned down ...
Here is a small adjoustment , wich in my opinion is not really good , but gives a small idea by comparing the two images.
I repeat is not how I think it shoul dlook , but just trying to experiment with tuning a bit more down the colors .
