First, listen to the Skyrim theme, during the part that starts at 2:09 http://www.youtube.com/watch?v=UsnRQJxanVM And then compare it to the Morrowind theme, starting at 0:07. http://www.youtube.com/watch?v=ZWuNf4gxwuM The diference between the two is that the Morrowind one is instrumental and slightly slower.
