Spoiler I really hated that Molag Bal quest. It did not make any sense, whatsoever.
And since it was my first Deadric quest, if I remember correctly, it really brought down my expectations for the others...
...Ironically, there are some quests that do give you a choice...
Spoiler such as that Mystic Dawn/Mehrunes Dagon quest
Another that I did not fancy was
Spoiler Boethiah's Quest. I still ended up with the quest even though I killed all her followers.
The writing in this game was not that great. Some things were good but the overall linear feeling really got to me. I ended up joining the thieves guild just to get the damn quest off my journal, despite the fact that my character does not respect the Thieves Guild (and failed in his attempt to assassinate the invincible members) and that Maven Black-Briar tried to kill him, though she ends up being rather passive about it, as if she never wrote any warrant?
The same with the Dark Brotherhood.
Also,
Spoiler I'm a Stormcloak... wandering Solitude without any worry. Standing before the queen, with the ability to shout... Looks like history could easily repeat itself.
Spoiler I also ended up with a quest that involved... eating people. I don't believe there were any dialogue options to avoid agreeing to the girl, but... thankfully, I was able to pull a fast one at the end of the quest, and kill her but not the guy. What surprised me were those who showed up, like the female store owner from the shop near the entrance of Markarth. I just finished returning to her, her Dibella statue. We got along just fine... until then. I was shocked. Her brother or boyfriend ended up finding out I killed her sooner than I got back for some reason.
I suppose it would be beneficial if there was a way to organize your journal. Then it would not seem like so much of a bother. I could just create a 'Don't Do These' folder and put them all in there.
