For some reason I've had this game for over a year, and never started playing it till today. I loved FO3, and other than the fact that it sometimes tells me I've "stolen" stuff after I kill bandits, FO:NV seems pretty good too. Its going to be my birthday in a couple of weeks and am probably going to get the wife to buy me some DLC on XBOX Live. So, I'm wondering which one to get first. If you could only have one of the DLC for this game which one would it be, and why?

ALL of them are amazing and all of them play completely different, but the thing is they have an inter-connected story. For that reason, they're best played in their intended order. That would put Dead Money as your first buy.

I will have to agree with Longknife you should get them all but if you can only get one at a time get dead money first. They tell a story so get them in order enjoy.

Old World Blues if you ask me...
