...Seriously, How is it possible for a "finished" game to have this many obvious bugs?...
Well, what you need to realize is that it's just
your game that is messed up. I play skyrim on PC and have never had any problems. It has done the random crash thing 3 times but that's the only problem I've ever encountered so it's no big deal for me.
I'm sorry, OP, for all the troubles you are having. I need to ask you a few questions. Have you killed a bunch of NPCs? Have you entered a lot of dungeons and caves before getting the quests that relate to them? What system are you playing on PC, PS3, 360?
