[*]I never even started the Companion's quest line.
[*]Never been a Werewolf.
[*]I've only been like a stage 1 vampire after curing myself almost immediately after being infected. Wrote a guide on the whole of Vampirism anyway.
[*]I've never married in Skyrim or even started the quest past the first amulet dialogue. Wrote a guide on it.
[*]Haven't played a single second of any of the DLC despite owning it all (basically because of college, but whatever).
[*]Never finished the Thieves guild quest line because that would mean giving up the Skeleton Key (which I've never used once).
[*]Haven't experienced any types of armor other than Daedric and whatever you start with. Started power-leveling smithing for it almost instantly.
[*]Haven't done like 80% of the quests people ask me for help with.
There's definitely more I'm forgetting.
