I am the one using ingame conversations, from Fallout 2, Fallout 3 and New Vegas as well as info from game guides. You are the one pulling stuff out of the air and passing it off as facts.
This all boils down to one thing with you. You don't like that the Enclave put all their eggs in one basket. Well to damn bad. Get use
So you don't like that the Enclave put all their eggs in one basket. svck it up and move on, because they did just that. There is a mountain of evidence to support what myself and others are saying. They were over confident to the point of arrogance and they paid the price for it.
There is not one instance in FO2, FO3, or FONV, where anyone in the Enclave says the rig and Navarro were the only Enclave base.
Richardson implies in game, there were several plans. Fact.
In FO3 game guide it says Autumn Sr, under orders of the president, went to RR, the only other Enclave base WITH a functioning ZAX super computer..
This sentence not only implies Richardson gave the order, but also the existence of other bases, albeit without a ZAX.
Fact.
And yes, because I do not believe the Enclave is dumb, and would follow BASIC COG and survival principles, I do not believe they put all their survival hopes on one thing. Just like there are multiple vaults, spread all over, various bunkers and shelters, I have no reason to believe the Enclave would abandon this basic principle for themselves.
