I've been play the last two entries in the fallout series recently, in particularly fallout 3 and it's add ons. I stuck my opinions on the politic stuff and rebuilding the world here.
Fallout: New Vegas and Fallout 3 (with all of the addons) political ranting stuff
The Pitt: As much as I hate to say it, Ashur is completely right about the brotherhood, in the sense they could be doing a lot more. Father Elijah, however insane he may be, had another good idea: Gather ALL beneficial pre-war technology, instead of just weapons. Another note about the Pitt: Who the fuck kidnaps babies? That was a huuuuuge deal breaker, and the antidote would most likely be handed out to everyone, as Ashur really respects and tries to care for the “workers”, and, it would drastically increase the overall ability to succeed of the Pitt as City-state/nation. That, however wouldn’t be enough. With the threat of trogs and wildmen being constant, as not everyone would be vaccinated (immigrants may not know until it would be too late), there’s also the threat of the irradiated water. The Capital Wasteland was enough of a horrible place WITHOUT diseases turning people into savage cannibals, let alone general air toxicity and insta-death radiation in the larger rivers (the game never alludes to how the Pitt received water, but I would figure it is from several smaller purifiers, as the area you explore in game is about 3~4 times more populated then megaton). He was right about almost everything but trying to bring the Pitt back, although if he had Brotherhood support they could probably put some resources towards installing more purifiers, and possibly a dam.
Point Lookout: Honestly, this isn’t a place that needs a government, it’s a place that needs to be burned. The swamp folk are too inbred and infected with the New Plague to do anything, and the normal residents here are either tribals getting orders from Calvert or just wierdos who live in isolation (which would be a mental hell in a Post-Nuclear world). What is odd though is how the Punga fruit grows here, and is fresh long enough to reach Megaton and Rivet City. I’d assume the only places Tobar himself ships to are Rivet City, the CommonWealth (maybe, I’m not to keen on where the institute could be located), and an unknown trading port, most likely. If it stays fresh long enough for him to travel from DC to northern Maryland in an old, dilapidated steam boat, and back to Rivet City, it’s probably one of the few chances the Capital Wasteland has at real agriculture (without any hydroponics, which, admittedly will always probably be part of agriculture everywhere in the wasteland), and getting onto its feet and becoming something like a nation. As for the actual gameplay and characters, Calvert should’ve been toasted a while ago when the light house ran out of power (actually he probably has a fusion generator somewhere down there), and the double barrel shotgun was a buggy piece of shit that you should never use ever.
Mothership Zeta: Not much on governments here, but I sure as hell hope that there weren’t any last second escape pods off of the other ship, or Earth is fucked. Again. I’d also like to note that Elliot Tercorien’s whole ordeal is actually pretty depressing considering what he has to come back to, and would probably have a downward spiral into Oblivion (c wat I did thar), very fun DLC, make sure you bring a ton of stimpaks and few weapons though (say, a 10mm submachine gun and a lot a lot of bullets, because you run out fast, and, when the shimmery shiny ones show up, something that inflicts fire or shock damage)
Operation: Anchorage: Wow, finally some insight into the Great War. It reminds me of all of the US’s middle eastern conflicts, only they’re a lot more upfront with the war for oil thing. Seeing the Kaiser tanks and such, one can really grasp just how desperate the U.S. was when they pulled out the nuclear weapons (I’m pretty sure we fired first and it was the last act of a desperate nation, as China stood a good chance at actually conquering us), and how advanced technology was. It’s odd, see the Mister Gutsy right behind you and then turning to see the photographer with that big, unwieldy camera snapping pictures of the infantry units. I always kind of thought the whole 50’s theme felt out of place, but Operation Anchorage really tied it together.
