.....yes I understand the lore, and 1950's was where FO timeline and our Timeline Deviated, things did not stay the same, FO's timeline beyond the 50's was the outcome if the envisioned *world of tomorrow* actually came to be, that said its not like the Strip would stay exactly the same as it was built for so long. I know its not our timeline.
But it's not exactly the same as it was in 50s Vegas. None of the Casinos are exact replicas. It's inspired by 50s Vegas. So it wouldn't have stayed the same. It would be constantly being reshaped and expanded like any other city. However, due to culture and therefore architecture stagnating, it would still retain a similar aesthetic.
Seriously? How exactly? (I mean... A mini nuke like that should obliterate areas from the game

)*But even so.. doesn't it take 4 or five of them to kill a behemoth?**As an experiment... Fire the Fatman at Mr. Burke in his chair in Moriarty's.
What does Mr. Burkey not die or something? Anyway, how do you know how much fissile material is contained within each mini nuke? You don't. So how can you say how big an explosion it should make? Granted, realistically it should be impossible to create such a small explosion with a nuclear weapon. There just isn't enough stuff there for it to reach critical mass. But there are tons and tons of other things in Fallout that don't make scientific sense, and yes, in the originals as well. That's why we have SCIENCE! to explain them because science says they're impossible.
Do you honestly not see how easily it could be exploited with the waiting system?
Maybe they could set it up so the recharge time was based on the "time spent playing" clock rather than the in game clock. Of course, I wouldn't expect it to take a full 24 hours to recharge, but perhaps the game equivalent of 24 hours.
