The Script is great in it, so many different characters all with great lines. Even from the courier,
The area is large to explore, new enemies, the lobotomites act as the contents raiders, at level 40 these guys were using brush guns and hunting revolvers and 10mm SMG for ranged, and shishkebabs for close quarters.
A bit about the gameplay. No companions, can't bring any with you, nor are there any in the content. You get to keep all your gear, and you are not limited to what you can take in, and you get a base of operations which you can store stuff.
I prefer it over Honest Hearts, because Honest hearts didn't really do anything special, but Old world Blues did. Next Lonesome road where we should meet the courier who was originally supposed to take the Platinum chip, and which every single DLC has foreshadowed.
