The AI's pathfinding is still kind of wonky. Don't get me wrong, it's much better than it was in Oblivion, but it's still a bit weird.
The graphics are good-not-great. I do like them and the aesthetics are particularly interesting, but they don't blow me away. The demo made it look like they would.
Magic is awesome. However, I wish I could find a better flamethrower spell. The starting one is good for a little while, but goes to shit soon after. And I don't mean a firebolt, either, I mean a full on flamethrower with greater range and much more power. The same for Frostbite, Sparks, and Healing - I would like to find better versions of each. Note that I've barely scratched the games' surface at only six hours in, so I probably will come across something better.
The interface is gorgeous and works great, but why the hell can't I organize things by weight, power, etc.?
Finally, the kids. Why must there be kids in this game? I didn't miss them in Oblivion, and now they range from "slightly annoying" to "downright fucking despicable".
