Achievements are in-game awards exclusively for the Xbox 360 version of Oblivion, including Xbox One and Xbox Series X/S. They act as optional awards to be displayed on your Gamertag, accumulating a history of all your played games and unlocked achievements in addition to the Gamerscore received from each achievement. In short, achievements are simply your personal accomplishments.
Xbox 360 players can earn Gamerscore by completing certain objectives in Oblivion. In total there are 1000 Gamer Points and 50 achievements in the main game. 250 extra Gamerscore and 10 extra achievements are added by the Shivering Isles expansion. None of the official downloads add any achievements or Gamerscore.
All achievements in Oblivion simply require you to advance within a guild, other faction, or the main quest. There are 6 achievements for the main quest, 8 achievements for the Arena questline, and 36 for the remaining four guilds. No achievements can be missed in Oblivion, barring actions by you to be permanently expelled from a faction.
