Tried the demo. It kicked ass. They give you 45 minutes to explore the world once you get out to the surface which is the first reasonable time limit I've ever seen in a demo (other than those that don't have a time limit duh!). I don't like this kind of graphical style though.
I liked that I had to actually confirm that I wanted to attack civilians as opposed to the likes of Morrowind where you can accidently hurt civilians because they just happen to casually stroll between you and guy you're shooting fireballs at.
