I learned by experience that the beasts of Skyrim can be more dangerous than the men. I set the horse on fire, slashed it, but it kept coming, so I ran. And it followed. I ran past some wolves, killed them all, and still the horse followed me. I finally lost it by jumping over some rocks, up the mountain a ways, and then jumping off a ledge to a lower area, hopefully confusing the crazy demon horse’s path finding AI. It worked, but for the rest of the hour demo I felt like I was being stalked by that horse.
