who made oblivion

The Elder Scrolls IV: Oblivion was developed by Bethesda Game Studios, a United States-based software company. The game was co-published by Bethesda Softworks and 2K Games for its initial Xbox 360 and PC releases, with Ubisoft co-publishing the PlayStation 3 version in Europe. Development began in 2002, right after the release of The Elder Scrolls III: Morrowind, and the game was officially announced in 2004. Ken Rolston, who was the lead designer on Morrowind, oversaw the development of Oblivion. The game features advanced graphics, improved AI with Bethesda's Radiant AI system, and physics powered by the Havok engine. Composer Jeremy Soule created the game's score
