Elder Scrolls IV: Oblivion is a first-person perspective fantasy computer role-playing game set in a vast 3D world with an open-ended storyline that allows the player the freedom to pursue the main quest, side quests, or simply explore the world. The game is set in a different geographic location from the previous in the series (Elder Scrolls III: Morrowind) and in general the architecture and wildlife is more medieval and real-world. The fantasy game art is vastly improved, however, and at the time of its release wowed the world with its realism and attention to physics in its interactivity.
