I have been trying to get passed the mountains to the west side. But it seems as there is one huge invisble wall from north to south blocking the west side. Is there nothing behind it? Will there come something with a DLC?? I also read some people couldnt get in the East side. Where I havent gone yet.
These blocked parts make the map much smaller :sadvaultboy:

And the DLC is XBOX360 exclusive now

Ya this game is much smaller then FO3, not only is the map smaller, half of it is inaccessible, most of the western part and some of the eastern part, the only thing thats on the east side is the Legion's tiny fort. Not to mention you could explore everything that was visible on FO3 map & the sewer/subway system alone in FO3 could match the entire size of pathetic tiny New Vegas.
