Its pretty impressive how much they managed to do with it. At first the video might seem a little underwhelming but then they move on to less barren areas and the ammount of detail they managed to squeeze in becomes far more apparent.
One question though - was it the optional high detail dwemer armor that can make you look like a robot bumble-bee?
