The length of playing The Elder Scrolls IV: Oblivion varies greatly depending on your play style and how much content you want to explore:

• For just the main story, it takes about 16 to 27½ hours to complete the original Oblivion, and about 15 to 20 hours for Oblivion Remastered

• If you include main story plus side quests, expect around 45 to 85 hours for the original, and about 30 to 40 hours for the Remastered version

• For a completionist run, which involves doing every quest, exploring fully, and completing expansions, the time can extend to around 184 hours for the original and 80 to 100+ hours for the Remastered edition

• Some players report spending 150 to 200+ hours in the game world if playing very thoroughly or leisurely

In summary, a typical playthrough focused on the main quest takes roughly 16–27 hours, while a full completionist experience with all expansions can easily exceed 100 hours, reaching up to 200 hours or more depending on your pace and exploration
