- I've never completed the Fighter's Guild. Once I got as far as killing some rats, which apparently was not the appropriate response. I looked around for an Extra Comfy Pillow, didn't find one, so walked away and never looked back.
- I've never done all of the Daedric Shrine quests. I don't even know who all of the Daedric gods are, I'm usually just interested in Azura's Star and the lockpick and Sanguine's quest just because it's amusing.
- Told the Grey Prince about his lineage. I just felt so bad for the guy and sometimes it's better not to know things.
- I've never jumped off Dive Rock. I've seen videos. That's enough for me.
- I've never managed to not piss of Fathis. I don't care if he's a guildmate, he's just not in the right here.
- I've never played as an Argonian or an Orc. Or a Redguard. Or an Imperial. And I've never had a character who used heavy armor or two handed swords.
- I've never done anything with Battlehorn Castle. I'm pretty sure it's included with all the DLC stuff. It should be there... somewhere (?).
Things I've recently done, only because it's kind of bugging me that I've never done them before:
- Using alchemy to make a potion.
- Completing Umbacaro's quest. Heh... silly little man.
- Kill Umbra. (Not sure what to do with the sword now.)
- Found Mehrune's Dagger. (I paid extra for this?)
- Saw the Giant Mudcrab up-close and in-person.
And mod related - I've never seen Kvatch Rebuilt. I really, really want to see that... almost enough to go through the MQ, even if I have to close those gates by hand with the console just to get it done. (The planes of Oblivion are probably my least favorite part of the game.)
So what have you never done? Whether it's because your character has never stumbled upon it even though you know it's out there, or it's just something you avoid out of personal preference, what have "you never", in Oblivion?
