Love the game, I've done the grand majority of the quests and still love to play through on multiple characters. I don't have xbox live or Internet access at my place at the moment so I still haven't gotten the patches to fix the major bugs yet so every now and again I'll have to reboot or give up on a quest line. Damned bugs.
All in all it's an amazing game and I'll probably play it until the end of time or I get aggravated enough with the errors to destroy it.
