Shivering Isles is just what gamers that played the $#!% out of Oblivion need

I have had Obliviion for no less than a year and there is one point around the 500 hour mark where you just run out of quests to complete and people to kill (or knock out). Shivering isles adds about 200 more hours not counting just staring at the beautiful scenery. If only the plants and creatures in oblivion looked this cool. The sound is also very good from the birds chirping to Sheogoraths drunken laugh. And I also enjoyed the look of the new clothes, weapons, and best of all is the costume you get when you beat it. and Even if you moderately enjoyed Oblivion you will just have to see the Isles to believe the Isles.
