oblivion

The Elder Scrolls IV: Oblivion is a 2006 action role-playing game developed by Bethesda Game Studios, and co-published by Bethesda Softworks and 2K Games. It is the fourth installment in The Elder Scrolls series, following 2002's The Elder Scrolls III: Morrowind, and was released for Microsoft Windows and Xbox 360 in 2006, followed by PlayStation 3 in 2007. Taking place within the fictional province of Cyrodiil, the game's main story focuses on the player character's efforts to thwart a fanatical cult known as the Mythic Dawn that plans to open portal gates to a demonic realm known as Oblivion.
The game continues the open-world tradition of its predecessors by allowing the player to travel anywhere in the game world at any time and to ignore or postpone the main storyline indefinitely. A perpetual objective for players is to improve their character's skills, which are numerical representations of certain abilities. Early in the game, seven skills are selected by the player as major skills for their character, with those remaining termed as minor skills.
Development for Oblivion began in 2002, directly after the release of Morrowind, opting for tighter pacing in gameplay and greater plot focus than in past titles. To design the graphics, Bethesda used an improved Havok physics engine, high-dynamic-range lighting, procedural content generation tools that allowed developers to quickly create detailed terrains, and the Radiant AI system, which enabled non-player characters (NPCs) to make choices and engage in behaviors more complex than in past titles. The game features fully voiced NPCs—a first for the series—and the music of composer Jeremy Soule.
Upon release, Oblivion was a critical and commercial success, winning a number of industry and publication awards. It was praised for its impressive graphics, expansive game world, and schedule-driven NPCs, and is considered one of the greatest games ever made. Following a number of smaller content releases, Bethesda released two expansion packs for the game—Knights of the Nine and Shivering Isles—which were bundled with The Elder Scrolls IV: Oblivion Game of the Year Edition in 2007, and later re-released as a fifth-anniversary edition in 2011. Oblivion was followed by The Elder Scrolls V: Skyrim in 2011.
