|The Elder Scrolls V: Skyrim||
The Elder Scrolls V: Skyrim is a role-playing video game developed by Bethesda Game Studios and published by Bethesda Softworks. It is the fifth installment in The Elder Scrolls action role-playing video game series, following The Elder Scrolls IV: Oblivion.
Skyrim's main story revolves around the player character's efforts to defeat the nordic dragon god Alduin who is prophesied to destroy the world. Set two hundred years after Oblivion, the game takes place in the land of Skyrim in the midst of a civil war after the assassination of the high king. The open world gameplay of the Elder Scrolls series is continued in Skyrim, as the player character can explore the land at will and ignore or postpone the main quest indefinitely.
