I am shocked at this. This is just the worst thing I think Obsidian has done. New Reno, probably the best town in the Fallout universe, not in a DLC! Area 51 is not in a DLC. All I have to say is wow! You make a game like Fallout based in Las Vegas and you don’t add Area 51. WTF!?!? I am just appalled at this, and I will never forgive this, truly. Sure it is a game and still a good one, but not doing some obvious things; in addition, many people wanted them.
New Reno, though a nice locale, seems a bit redundant when you conisder that The Strip carries some of it's themes.
Area 51, might seem like the obvious thing to do, but they probably didn't want to go for the obvious and bring their own stuff to it. They did that with OWB.
Overall you are deluded to think that they is some sort of affront to your sensibility. They can do as they please with their DLC.
