Now then, tell me, if you really think the maps are the same size in NV and F3 then you are right! But at the same time you're wrong! Here's why: the maps are basically the same size, BUT you can't go where the map says you can! Jacobstown is the farthest west you can go (besides charleston cave) and the farthest north you go is shortly passed new vegas and nellis airsforce base. Plus, I have spent about 50 hours on this game, and have found SO many locations, and have two profiles: a level 20 and lvl 19.
So do not in any way think that my opinions are biased. Let me start out by saying I love fallout new vegas more then F3.
