The world in New Vegas feels cohesive and like an actual post-post-apocalyptic place (though, admittedly, it's not like Fallout was known for being serious after FO2 and the west coast had already had two protagonists help get it to that state); the towns make sense; the factions are fighting over legitimate stuff; the characters and their wishes, desires, shortcomings and so on all feel "right". I can take a stroll around the Mojave for the zillionth time and go "Yep, this seems fair enough", but the Capital Wasteland? N o p e. Megaton and several handfuls of other stuff seemed so silly on first encounter, but holy shit, I was not prepared for Little Lamplight - it being a reference doesn't mean anything when it's part of the main questline - Bethesda worlds are theme parks with amusement rides scattered about instead of legitimate worlds with valid, albeit sometimes "less than exhilarating", locations; I can't fault those that just want their zany lolsofallout humour and heavy combat focused Fallout video game with something CRAZY happening around every corner, but I like to really get into the world (and I'm biased having already had a vested interest in west coast Fallout happenings) and immerse and I can't do that so well in Bethesda Fallout, as they showed me again with FO4. I can enjoy them in the same way I would with watching any random popcorn flick, but I don't have that same draw with them that I do with New Vegas, not even remotely.
