There are tons of great details in the game. The little beetle armies in the Catacombs are one of them. I was horsing around with a low level char yesterday and found myself amazed at the level of detail put into even basic equipment. My guy was wearing chainmail, and if you stand near a wall and get the camera in close, you can see spots along the shoulders where the armor was actually sewn together at the seams -- i.e., the sleeves were sown onto the links for the shoulders etc. Again, for a piece of equip almost nobody ever uses, at a level of detail almost nobody would ever even see. And his basic hollow solider helm was reflecting random bits of scenery around him, again only visible if you zoomed way in.
