There's no resurrecting the emperor, either. The only choice is to go back to my closest manual save, about an hour back. EXCELLENT DESIGN CHOICE. Why don't we lull the player into a false sense of security by saving every 5 minutes and then fuck them right over with dead end scenarios like your escortee not going through the door at the same time as you (wtf?) and being able to straight up die, forever, when the other dumbass npc with us just keeps getting "knocked unconscious" time and time again, only to rise 3 seconds later?
This is, of course, not to mention the game's larger issues, such as game-breaking monster leveling issues necessitating cranking the difficulty down all the way to play a character that focuses on anything other than brute strength and combat, a wholly worthless third person perspective, clunky combat, and the longest load times since, well, ever. Really, this game is good despite its myriad of attempts at self-sabotage. I hope Fallout 3 was left in the oven a little longer, figuratively speaking.
Edit: Went back and finished the main questline. All it took was getting through the door without a glitch! I'm counting this as beating the game. I want to go and finish all of the guild quest lines as well, though.
