Assassin's Creed Unity honestly looks a lot more impressive, especially because the hair on their characters doesn't look like the end of a mop.
Still looks really impressive, and without a doubt will play a lot better than Unity, but still going to have to see it maxed out on PC first.
Have we been told what platform that last footage was from? Still assuming it was Xbox One footage, right?
Skyrim is also the only game I own that legitimately doesn't work on my computer because of my monitor.
So there's that.
Edit: Actually, I take the Unity thing back. Unity loses a lot of points on visuals because of the crazy low view distance, and how blurry everything gets.
