Someone the other day mentioned that they had been looking at pictures of deserted cities for several hours. I came across this today, and the pictures of Battleship Island made me think how astonishingly well done the game art in Fallout 3 was. In each of the pictures, you kind of think "Oh, man, I bet there's a super mutant machine gun nest around that corner."
Further down in the post are some pictures (and some links to some video) of Kowloon Walled City, which brought to mind Ridley Scott's Bladerunner or maybe Bioshock. Definitely some interesting stuff.
