So, since we're on the subject of science fiction (and evidently have been since 2016) I have a couple things to add, and also a request for just a little bit of help.
I grew up (yes, I know that's sometimes hard to believe) being a Buck Rogers and ST:TOS fan. Just because of timing and when things were being broadcast, I didn't get into Battlestar Galactica until what would be their "second season", i.e. the dreaded (and later disavowed) Galactica 1980. It wouldn't be until mid-way into the 1980s that I finally saw the first season of BSG, and of course how can you not fall in love. But anyhow...
Time passed, and of course I watched a lot of the other stuff and things also not mentioned yet in this thread, and then after a LOT of years went by, it was 2000, and a British guy named Neil Adams wrote a crossover fan-fic between 70s BSG and Buck Rogers. It kept me up late reading it, I can tell you that much. Of course, it has a LOT of little issues with it, and it recycled stuff we've seen elsewhere (and previously in either series) so it's not perfect, but the germ of the idea really occupied a lot of my attention for a few years because I started working on a writing project to continue the story when it became evident Mr. Adams (who I've tried to contact several times but failed) wasn't going to continue it.
Anyway, here's where I'm at (and I'll try to make this as brief as possible).
70s TV at its best was not even remotely as sophisticated as Babylon 5 in the 90s, or NuBSG in the 2000s (or a LOT of other things). And if we're being honest and objective, neither BR nor BSG was the "finest" which the 70s had to offer. Moreover, there were lots of really irritating things in BSG (terminology especially) and just so much was left out or never really thought through. Back when I was originally working on my writing project, I generated probably a foot-n-a-half (not quite half a meter, for our non-US friends) of pre-development material and sketches of ideas, all of which would do a lot more than just make the series (both of them) more sophisticated.
Fast-forward to this morning. I was out for my early morning bike ride before work and was thinking about food and supplies in the Buck Rogers universe (I recently picked up the project again and am posting it on fanfiction.net) which then kind of led me into a long thought process (which I won't repeat here) about the effects of a ca. 1980s nuclear WWIII. When I got home I started googling maps and looking for photos and other things, and anyhow I'm wondering if there's materials out there which might suggest what a post-80s WWIII new world order might actually look like. It's not that I'm either incapable or not inclined to work something out myself; I'm just curious what actual experts in the field may have suggested.
For example, everything I know tells me WWIII would be a northern-hemisphere thing. Obviously there would be tons of radiation traveling over the ENTIRE globe, but the southern hemisphere would probably be in better shape. Who knows: Brazil or even Columbia could become the new western hemisphere power brokers.
So, does anyone here have any insight or even just some really good links for this sort of story-background-development materials?
Oh, and btw, here's some links for those who might be interested:
