I would think someone that doesn't want their experience to be too "controlled" by the developer, would choose the pc version over a console version. It seems to me that you forgot about that when making that choice and now you're pissed when you mainly got yourself to blame for that.
Did you bother to check what you could or couldn't do without mods, before buying, to see if you could get the kind of experience you were looking for, on that platform?
By saying you could have bought the pc version, I don't see how your anger towards the developer is justified when it was your decision to go for a less customizable experience.
I didnt expect Bethesda would do something as [censored] as making so many npcs essential.... Main quest i think its fair they're essential, but with every other quest i just think its lame...
They should have made it so that if you kill someone who is part of a quest, some other npc will step in, in its place. I was told this was a feature, but appearently i was decieved.
