It got me reminded of all the concept art that was shown to us earlier. When a fairly large creature is slain, like a mammoth, do you think their body should stay there and slowly decay? Like in this picture http://zoknowsgaming.com/wp-content/gallery/elderscrollsvskyrim/elder-scrolls-v-skyrim-7.jpg (its cool how the mammoth has been dead for a while and is slowly sinking into the snow)
So far the game looks incredible and can't wait to try it on my PC but a really cool feature would be that not just dragon carcasses are left behind in the game.
