Wow... so much tryhard hate towards NV. Trying to be some new kind of edge-lord, Someguy? Because none of your points actually work It's still set in a world ruined by nukes. It's just that Vegas fell apart due to complete societal collapse and anarchy as a result of said nukes destroying all form of conventional civilization. It's still post-nuclear but only because society fell apart as a result of nuclear war, not directly due to nuclear war. EDIT: Nope, you did not cite proper sources (discussions and forums, really?) and uses Wikipedia of all things for definitions. It does not prove anything except for your love of cherry-picking points that suit their agenda (and willfully ignoring others who disagreed in said discussions and forums) which anyone could do but knows better to not do. Assessment: "Enough said" is too preemptively . EDIT: In fact, I can copy your MO too except I will pre-face it and acknowledge it as a discussion rather than conclusive proof; here is a link to a discussion on Reddit on post-post apocalyptic world building and examples of it: https://www.reddit.com/r/worldbuilding/comments/3b01i2/postpostapocalyptic_is_that_right/ I like how you purposefully ignored other people who disagreed with those headlines/topic titles and argued back against it but go ahead and maintain your narrative for your own agenda. It is clearly 'not' disingenuous and not misrepresenting the truth but go ahead and keep lying about it. The world is a post-post-apocalyptic world like @R.Graves said. The world has recovered from the nuclear apocalypse and some of its consequences (not all, like lawlessness and hostile environments) to rebuild. Keeping it post-nuclear after 200 years has passed keeps the franchise and setting quite stale and underdeveloped. You clearly did not read the part where it was mentioned how Mr House forcibly united the tribes and had the New Vegas aspect of Vegas rebuilt and restored to astound newcomers like the NCR. Plus look at Freeside; that area is in ruins with a few buildings restored and some completely rubble. The world was reset by the Great War and recovered since then to the point of new nations forming. Nations in need of new lands and resources. The Mojave region is mostly untapped (with Hoover Dam in mind) and since the world is a post-post nuclear apocalypse one, the Mojave is a new frontier like the rest of unexplored America. Why else would there be expansion towards new territories if not for similar reasons to what led to the kind of emigration that created the American Old West? Plus it would be time to get new tracks to fit the new elements and shift with old tracks still in it to make some kind of post-post-apocalyptic Western. A hybrid of post-apocalypse and Western with a touch of concept advancement since the world is clearly no longer a fresh post-apocalyptic one anymore (plus the whole Bethesda wanting their timeline and all). Also, the actual areas hit with nukes in the base game begs to differ since they do have substantial levels of radiation for a setting that seems to not pull off 'post nuclear'. In addition, there is a lore reason for the region being different than others; an excuse perhaps but a pretty good excuse all things considered. That does make me wonder where the series can go after New Vegas (and discounting 4 which did not go anywhere but merely wallowed in one spot). New energy and/or food crisis for the NCR? Legion lands in civil war? Expansion to lands beyond the North American continent?
