Shivering Isles is an expansion and I'd recommend it. If you wanted true addons, should of went for PC.GodLovesDead

Yea I aagree with G.L.D, I believe shivering is best but for a vast amount of add ons I would have gone PC.

I always find myself exploring Oblivion every now and then. Can never get tired of that game.War_Martyr

Totally agreed. I pick up my Oblivion every once in a while, same with my crackdown I just love those games.
