Because I think it kind of applies here in this continued discussion about the plausibility or ridiculousness of the NAN ever happening in the first place (and/or about how more recent writers "should" handle it), here's a post I tossed up over on RPG.net the other day that sums up my feelings not only about the NAN but about some of the SR1 silliness in general:
QUOTE
The balkanization that occurred to make Shadowrun possible, way back in the first edition days, is perhaps one of the things that gets "overthought" more than anything else. Don't sprain your brain trying to make sense of Indians taking over most of the continent, the South rising again, the Northeast and Canada tying themselves together at the waist, CalFree as the whipping boy, Aztecs taking over most of South America, the Japanese resurgence in a neo-feudal tradition, Germany breaking back into a bunch of little mini-states, Tir Tairngire, etc, etc.
Attribute the breakup of nations to the rise of megacorps, and just let the Rule of Cool smooth over the rest; trying to make sense of it all now, twenty years after it was written -- or even worse, expecting the writers to do so -- defeats the purpose.
Love it for what it is, pure silliness. Everyone that had any sort of old stereotype suddenly got magical and lived up to it (Native Americans, South Americans, every East Asian nationality, the Irish, and on and on), and they tacked on, later with official Earthdawn links, old stereotypes for a few magical races (Elves), to boot. They turned back the clock on every ethnic group in the world until they hit something awesome and then they turned that flavor of awesome into a megacorp, a nation, or a hybrid of both.
Looking at it now, when we're all twenty years older and smarter, does it a disservice. Love it for the goofiness that it was, and have fun playing in their sandbox. Everything else is taking it too seriously.
Don't worry about why the yellow sun makes Superman do what he does (or why every other Kryptonian didn't book it to a yellow-sun galaxy instead of hanging out on a dying planet). Don't think about how crazy Batman has to be to prowl the nights (or about how weak Arkham Asylum must be to let his equally psychotic bad guys out time and again). Just read the comics and have fun, y'know? Make a leap of faith, willfully suspend your disbelief for a little bit, and enjoy the universe.
