The fact that I had no choice about selling my soul to Nocturnal to finish the questline probably wouldn't have bothered me if I'd come across it in another game. But Skyrim is a game which prides itself on player choice and freedom to roleplay. I am completely okay with Nocturnal extracting a price in return for her help, it just bothers me that the game abruptly takes away my ability to say no.
I think it's bloody hilarious that Karliah goes on about needing Nocturnal's blessing to defeat Mercer-- and all the while I'm thinking... ummm... I can just reload if I die, and you don't even need to be there, honestly.
All that hog-wash about the Thieves Guild being so unlucky since the theft of the Skeleton Key definitely leaves much to be observed. What luck? Skyrim doesn't have Luck! It also lacks any semblance of perceived Luck related hinderances in looting/mugging upon acceptance into the guild... I can't make sense of this twisted psychosis Karliah exhibits.
...course... it is possible that in any reality that a prospective Dragonborn exists in and, by chance, favours notoriety in deceitful, cunning, and/or relating to various
bad samaritan acts; it is in that existence all possessions of Skyrim's people degrade to a standard of value equal to that of any other manifesting, existing, unexisting, and past or retired Dragonborn, respective to Thieves Guild association. I'd be ever so titillated by a pondering of such gravity. A reality where an absence of a Thieves Guild were existent would, surely, be a grand venture for any persons wishing to plunder and loot as thieves do!
I have the exact same problem with the Companion's questline. Not only does it force me to become a werewolf to continue the questline, it also forces me to participate in the slaughter of an entire fort full of Silver Hands to 'celebrate my transformation' without giving me the chance to say: "Um...Aela...I thought we were supposed to be honourable warriors. Also, I think I've figured out why the Silver Hand hate werewolves so much."
I have yet to do any of the Companion's quests directly as a result of this. So, you mean to say I can become a Companion and act thusly, but to do so I must become a werewolf? Is there not anyone else I can talk to about this? I'd rather not become a werewolf just to query you about a cure later on... A polite refusal for bloody insane wolf-people must be in the Dragonborn's capacity by level 70 Speech, at least.
Edit: Oh, sorry! OT: I have never done a single Thieves Guild side quest. I do not have the patience for it-- unless the Stones of Barenziah count... I've done that several times.
