So, the new Thief kinda sucks . Shame, but then, this isn't a feature about AI programming, or level design. It's about art, and the art for the game was great.
A little monotonous, perhaps, since everything is dark and busted, but then this is a Thief game, not Katamari Damacy.
All the images you're seeing here are, now that the game's out, also available in an art book from Titan Books.
You can see some more art from the game in this earlier post.
