The cages with the gas bottles in, the signs outside shops that are the flexible plastic kind with the heavy rubber base, the fence near the start area not a kind you'd commonly have seen back then. Also the road signs don't look right, and the Yaughton village sign. Other than that the detail seems very sparse and copy and paste. I dunno just not blown away by this aspect of the game to the extent I was given to expect.
That feels rather mealy-mouthed considering what they get right. It is absolutely stunning and I've spent ages studying so much of it so far.
The story itself - is ok. I feel like I'm near the end but it's not totally enthralling.
