I don't know, Skyrim and Oblivion never had any re-playability for me, once you had completed the content there was no real reason to re-play the games as there was nothing you could really do that differently. I think this is where Dragon Age Origins really shines. Even though the game only lasts 40 hours and Skyrim 100 I re-played Origins 10 times at least which made it last 400 hours.
