I'm all for upping the density in any given area or scattered through the entire wasteland, but let's say I'm at one end of the map and need to get to the opposite side -- sure there's a lot to take in getting there, but if I want to skip all of that for now, it would still seem bigger if it wasn't lacking in square mileage. Bethesda just has to make the proper balance of the entire world. I don't mind if a few of the cells are quite barren as long as it seems realistic even if there was just one shack or one swingset. I thought anyone talking about size would be thinking of stretch of the land, not the content. I'm quite positive the content will be plenty and varied. A larger world space wouldn't make it all feel crammed together at the same time.
