Completed Lonesome road today, not sure I'll be entering the divide again though, mind you, having said that, I'm not sure I'll be returning to the locations of any of the DLC's, everyone I've played have left me with the feeling "glad to be back home" after finishing them, but lonesome road more so, it actually left me feeling a little depressed, I'm not knocking it, from a story pov it's quite good but lacked enough light hearted moments to balance things, if you like dark then it's a good DLC, I prefer a balance myself, by the time I reached Ulysses I just wanted to blow his head off and get out of there, it took all my will to stay in character, my current character prevented the launches believing the people have seen more than enough fall out from nuclear weapons, of course I got attached to the new ED-E and the choice at the end did not help my mood.
I'd be interested to read of your experience with lonesome road, did you feel satisfied, depressed, but more importantly, will you or have you play more than once?
