The game is supposed to take place in the year 2084 or so yet almost everything in the game is very present time-ish.
I haven't seen something futuristic in any map so far and the weapons also don't have something new to offer.
Maybe we need a team of concept artists or similar to improve originality and story consistency of all artworks.
But it would probably help heaps already if artists were more conscious of the fact that it's supposed to be the year 2084. Maybe stressing the fact when asking for an artwork would help.
Well there are probably more important things to do atm but the sooner we start inventing when creating artwork the better.
