You do realize your logic doesnt make any sense? In the "game history" its taken civilization over 2500(i know its more) years just to get to the point it was at before the great war. That was the Peak of human civilization. And with that war humanity was wiped off the face of the planet. And you just expect humanity to magically restore it self to the exact same point it was at in only 200 years? Well, sir i beg to differ, thats not how it would work (and as a matter of fact thats not how it did work). Also if you dont want Mr. Sawyer to compare actuall history to the games history, you should also try to refrain from doing so in your argument, it just makes you look like a hypocrite.
I guess the question at this point becomes this- "In the event of a global nuclear catastrophe, would humanity cease to exist?" In which case the answer is "No."
Another question could be this- "Given OUR real life history, on this planet, and all the experiences that it entails, does the game FO:NV accurately reflect our (in this reality) tech or educational advancement?" again, the answer would be "No."
Now, if you shunt the justification for spending your $60 for a product that may or may not deliver what it claims to, the question you NEED to ask is this:
"In light of the fact that human knowledge expands at an exponential rate, and given the framework offered by the previous games, including VERY advanced technology (compared to what we
as real people have), does a luddite army led by a megalomaniacal figure bent on exerting his will, with no reason other than desire, and more importantly,
no true will power, to actually see it through to its logical and tragic conclusion, make any sense in the universe as it is presented?"
Well, the answer again would be "No", for all the reasons I and others stated above, and plenty more. If you are going to completely base Caesar's actions on history, fine, and it might even succeed at that point, but when the character only uses that
as a basis for his "rule", leaving off bits that din't stroke his ego (which would be tenuous at best, given the circumstances), ignoring MOST of the things that made it operable, let alone successful, as happens in the game, well, then you have issues.
As for your "2500 years", well, I really need to ask: "When exactly do you think that folks from our version of the 1950s came up with laser and plasma weapons, especially since we (in real life) don't even have them now?" Would it have been year "0", or, perhaps closer to "year 2450?" To be honest, neither answer works in your favor, but cling to what you must.
If Sawyer can "take and leave" bits of OUR collective history in creating a game and its characters, then surely I can examine those bits with the same microscope...
