[Fallout] Instead of having some kind of an experiment or secret,each Vault is ''normal'' (Vault 8 pretty much) and is opened when the all clear signal goes out.How is the Wasteland changed?

The Vaults get their standard supply of a GECK and everything. (by the all-clear signal I mean Vault 8's Enclave one.)

Well for starters Civilization will probably rebuild a lot faster.
There are about 120 vaults. Each vault holds a couple thousand people.


If each are like Vault 8 then many of them will leave the vaults within a few decades and found cities like vault city. The ones that don't leave within a few decades are just in places with high levels of radiation.


Now with all these vaults opening and founding many cities across the wasteland the enclave will most likely soon show up and take control of the cities. Since  they created the vaults, the vaults would be loyal to the enclave.


With nothing to stand in its way the enclave will take over the wasteland. 


With 120 vault cities this New America controlled  by the enclave would become a sort of Utopia. Since as far as we know the rest of the world is a wasteland too then America will likely be better off then any county in the world. 


The medical technology of cloning and stimpacks as well as the military power of power armour will allow this new civilisation to deal with any threats it faces. 


They will soon be able to get factories working again. Factories that will be staffed by robots that will start producing everything from cars to power armour.


Places like Big MT will be discovered eventually and there technologies will be used to further progress mankind. The infinite  resources from the Vender machines  from the sierra madre    will allow for even more progression as humanity rediscovers space travel and travels to other continents.


By the year 2277 the enclave have most likely taken over most if not the whole world. Soon the will be able to start colonising and terraforming other planets. 


Humanity will keep expanding into space colonising and terraforming world after world. 


They will eventually meet the Zetans who will be greatly interested in some of the technologies on earth.


Humanity will start trade deals with the Zetans. Trading things like technology, knowledge and even planets. 


Humanity will expand through out the galaxy  becoming a galactic super power.


Humanity will live in a Utopia and there will be peace.
