So, this has been pissing me off for quite some time now. Before you begin writing, thinking, or even thinking about writing, have a look at this wonderful picture:

Do you think that it is okay that 38,2271% of the map is unreachable? (yes, i counted the squares).
Also, what could they have done to use that empty space?
Oh, and here is a picture of Fallout: 3's map to compare:

Yeah, I don't understand why people say FONV is bigger. Not only does it NOT feel bigger, it is not bigger. Also, even though there are more places on the map in FONV a lot of them are small and even just one little shack and some of those one building locations you can't get in to the building. The small locations in FO3 are not marked on the map and the large locations that are marked on the map are huge in comparison to FONV.
That might be, but they could still have easily spread the locations out more, so the huge space wasn't wasted. And for God's sake, put some random encounters in between!!!
Anyways, I'm still pretty sure that the amount of walkable space was bigger in Fallout 3.
Whether one is bigger than the other or not....I agree, Fallout 3 just feels bigger. It's takes longer to walk from one place to the other and more stuff happens on the way, whether it's random encounters or unmarked places on the map to discover.
You know what bothers me? Why can't I get up on the crumbled over passes? Like the one going up towards the Boomers. I tried and tried and there was no way to get up on it. :/
