I'd rather want multiple maps, say a dozen, each the size of The Pitt, or 3 maps 50% the size of Fallout 3's with a city like New Vegas (in size) in each.
But if I can't have multiple maps then I want the map to be 200% the size of Fallout 3's but with locations more spread out, it is a wasteland after all.
(I want bigger towns and cities and we can't have that if there is only one map the size of Fallout 3/Skyrim)
As to the locations, did you search for them all in one playthrough?
Cause I didn't. In all games I explore a certain amount of locations in each playthrough and I always have multiple playthroughs.
