Bethesda Softworks announced today that it will release The Elder Scrolls IV: Oblivion Game of the Year Edition (GotY) on the Xbox 360, PLAYSTATION 3, and Windows (PC) this September. This edition of the game will include the origional award-winning game, along with both the Elder Scrolls® IV: Shivering Isles™, and Knights of the Nine™ expansions of the game.

Allowing gamers to play the 2006 Game of the Year with additional content will most likely interest many that were thinking of buying the game. Along with that, people that have already got the game will be able to continue their existing games and experience the new quests and areas offered by the expansion and downloadable content.

With more than 30 hours of new gameplay, Shivering Isles allows you to explore an entirely new plane of Oblivion – the realm of Sheogorath, the Daedric Prince of Madness. Shivering Isles features a bizarre landscape split between the two sides – Mania and Dementia –filled with vast, twisting dungeons mirroring the roots of the trees they are buried within. Sheogorath himself looks to you to be his champion and defend his realm and its inhabitants from destruction as you discover all new items, ingredients, spells, and much more.

Knights of the Nine features an all-new faction and quests for noble characters and answers many of the questions surrounding the Ayleid ruins found throughout Oblivion. Players can join a new faction and found their own order of holy knights – leading them into battle against a sorcerer-king and his demonic minions while exploring massive dungeons and searching for legendary relics – the holy armor and weapons of the Divine Crusader.
