Since I apparently love punishing myself with insane challenges, I've started a challenge run of Oblivion. The rules for it are simple
-Has to be played at the max difficulty at all times
-Can only use Hand to Hand combat to damage enemies
-No armor allowed
-Can't regain health from drinking potions or healing spells, only from sleeping
-Can't have followers
-Can only save after sleeping in an inn
-Have to complete optional objectives in quests
I win once I beat all quests in the main questline, the Fighters Guild, the Mages guild, the Thieves Guild, the Dark Brotherhood, Knight of the Nine questline, and the Shivering Isles main questline.
