Radiation is the effect, fallout. It isn't all "BOOM", the menace of nuclear weapons is that they make places unlivable. Boom is secondary.
That didn't answer any of my questions. Hiroshima and Nagasaki are not wastelands today. You need to demonstrate that nuclear fallout would have effects significant enough to prevent any development for 200 years.
And for Ghouls, not all Ghouls are created straight away, some Ghouls like
Spoiler Moira if you blow up Megaton
are created afterwards. Also the very likely small Ghoul population would of had to contend with the Super Mutant threat, other Ghouls being hostile and other mutating creatures.
You meet ghoul's in Fallout 3 who specifically talk about surviving the original war. The threats then would hardly be different then the threats now. If anything, now having to contend with human scavengers and raiders would introduce
greater risk.
Yet we are talking about the same world, the Brotherhood of Steel and Enclave developed outside of the area the game takes place. Just because the NCR developed on the coast, doesn't change the fact that virtually nothing happened in the New Vegas area in those two hundred years either. Heck New Vegas by some people's logic should have become a metropolis of civilization in those two hundred years, especially considering that virtually no nuclear weapons fell on it thanks to "laser defenses".
You're missing the point. It's not that there isn't a large degree of industry or government, it's that there have been no development at all. Thee are some scattered farms, but no one seems to be using them. Where is everyone getting their food? Are they really still making runs on abandoned supermarkets? Survivors haven't even bothered to clean the trash out of places they
live in. Even the tribes and raider groups in New Vegas have roots in the area.
