The Elder Scrolls IV: Oblivion Game of the Year Edition presents one of the best RPGs of all time like never before. Step inside the most richly detailed and vibrant game-world ever created. With a powerful combination of freeform gameplay and unprecedented graphics, you can unravel the main quest at your own pace or explore the vast world and find your own challenges. Also included in the Game of the Year edition are Knights of the Nine and the Shivering Isles expansion, adding new and unique quests and content to the already massive world of Oblivion. See why critics called Oblivion the Best Game of 2006.

In the Shivering Isles expansion, see a world created in Sheogorath's own image, one divided between Mania and Dementia and unlike anything you've experienced in Oblivion.

The Knights of the Nine have long been disbanded. Reclaim their former glory as you traverse the far reaches of Cyrodill across an epic quest line. Vanquish the evil that has been released upon the land. New dungeons, characters, quests, and mysteries await.
