The Elder Scrolls V: Skyrim is a 2011 action role-playing game developed by Bethesda Game Studios and published by Bethesda Softworks. It is the fifth main installment in The Elder Scrolls series, following The Elder Scrolls IV: Oblivion (2006), and was released worldwide for Windows, PlayStation 3, and Xbox 360 on November 11, 2011. Skyrim was developed using the Creation Engine. The team opted for a unique and more diverse open world than Oblivion's Imperial Province of Cyrodiil, which game director and executive producer Todd Howard considered less interesting by comparison.
