It is frustrating that I can not open a post everyone can add so we can all to it and expand on it what NMA would have done with Fallout 4 and what our interpretation of it would have been.
I will try to keep up with all your suggestions and incorporate them into this post as I expand it.
So for our entertainment (and to show that fans can indeed be smarter than an actual paid game designer) I present:
"Fallout 4 as it would have been by No Mutants Allowed members"
Background story: set of the ruins of the former Commonwealth of Massachusett at the former United States' East Coast. Like much of the rest of the United States it suffered severally from the nuclear attack that ravaged most of the inhabited part of the planet.
The Commonwealth was one of China's missile command's primary targets due to the significant present of military installations and industrial infrastructure as well as several large population centers.
Some manage to survive the nuclear onslaught by fleeing to the Vaults, others such as the Commonwealth Institute of Technology's staff, professors and researchers, students, and some of their families to take shelter in an underground complex which construction was funded by donations of wealthy and powerful ilumni such as Mr House.
The remainder is trapped on the surface and has to fend for itself.
In the years after the bombs survivors on the surface come together to form new settlements, tribes, and raider gang that prey on each other for survival.
The survivors notice a huge number of unusual mutations taking place throughou the commonwealth, insects and arachnids for example growing to larger sizes and their venom potency actually increasing than decreasing.
For a long time most of the Commonwealth remains an uncivilized and anarchistic wasteland where the strong rule, but survivors from the former police, national guard and survivalists gather together to form the Minutemen, an organization taking its name from the original US civilian militia that formed to resist British rule. Their goal is to protect the peaceful inhabitants and settlements from the raiders and mutations that plague the Commonwealth.
Settlements start to increase in numbers and more organized trade starts to take place between them, giving rise to salvage and reconstruction activities; a new society starts to form in the Commonwealth.
Places like the Combat Zone appear that appeal to those interested in watching or participating in combat competitions that sometimes only end with the deaths of people.
Around eighty years ago the Institute resurfaces and representatives make contact with leaders of settlements and the Minutemen, offering their advanced knowledge and technology to assist in the rebuilding of the Commonwealth and establish a new civilization.
The Institute starts to hire salvagers and scouts to search the Commonwealth for useful resources and determine the state of previous industrial sites such as factories and power plants.
Around this time the robot races in East City Downs are established by technicians, becoming a popular form of entertainment and betting for people in the Commonwealth.
Even the Institute starts to sponsor the races, providing technically training and robots for those people who would like to participate in them.
This was done on the urging of members of the humanities department of the Institute to provide a source of entertainment and boosting of moral for the people and to create an alternative to the Combat Zone that becomes increasingly notorious for the visceral combat that takes place there.
In time terraforming of the most irradiated parts of Boston starts to take place and on its ruins a futuristic 'City of Tomorrow' is being constructed by Institute robots and laborers from the surrounding settlements. The city is settled by both the Institute and a population of surface dwellers and becomes a symbol of a new future for humanity.
Unknown to the civilian population and much of the Institute researchers in the original Institute shelter are working on another project next to their work on rebuilding the surface world; creating the next step in robotics in the form of androids.
Originally just a side project its development takes a rapid pace when Institute scientists and engineers are able to recreate the matter reconstruction technology that was first created by Big Mountain. With almost unlimited resources available now the scientists and engineers invent and perfect microchip technology and advanced integrated circuitry, leading in advances in various machinery, gadgets, and computers.
The Institute is able to make computer brains more smaller than even Pre War technicians were capable of at the height of US civilization.
Along with studies in recreating the fom of the human body it rapidly accelerates the android project and when the first models tried out in the test labs are reveal to be stable and of great support use to the human population, the Institute leadership authorizes manufacturing and further refinement and improvement of the androids,
These improvements lead to even more human looking androids which are some point are rebranded synthetics or synths.
In order to make them more human and easier to interact and instruct computer scientists and psychologists start to create a computer model that allows a synth to think relatively similar to a human. Development is even done to make the synths simulate emotions so that people in general find it easier to work and interact with them.
Some of the Institute scientists, in particular Artificial Intelligence experts but also experts in soft sciences such as history become alerted by this development, warning that as the synth neural networks become more complex that it may reach a critical point that independent thought is possible.
Their fears are only increased when Institute Security starts to employ synths as guards, greatly expanding the Synth's capability of understanding and performing aggressive actions.
A movement forms that urges the Instititute leadership to limit the development and manufacturing of newer and more advanced androids, and recall the already operational ones to undergo modification to limit their though processes and make them incapable of performing any kind of combat.
The Institute leadership hears them out but denies their request as the Institute becomes more dependent on synth labor and support for the terraforming of the Commonwealth and the maintenance and expansion of the city.
The opponents to Synth development's fears become true when some synths start to perform action they were not programmed or instructed to do so, or go to places where they are not suppose to be.
Programmers who study the data from these rogue synths minds discover that the synths are starting to program themselves. Worse, the synths are more and more loosing the distinction between themselves and humans, designating themselves or other synths as 'human'.
The Institute leadership by now even becomes worried as the warnings of the opponents of the synths are coming true. They decide to give the order to recall all synths that emulate humans the most and put severe software restrictions on the mental capabilities of the more artificial ones, but the decision comes to late.
The networked synthetics have come to see themselves as the next generation of humanity; humanity 2.0 created in the image of the creator but that is stronger, faster, more intelligent and less inclined to fight amongst itself than the old humanity.
The fear and actions of the Institute only proof to them that co existence with the old humanity is next to impossible, the weaker humanity will always seeks to control and limit them.
The sign for a revolution that was already in the making for some time is given and the synths all start to rebel against the humans in the city and the Institute shelter and various battles break out.
Most of the human inhabitants are killed in the first hour but remainders consisting of scientists, technicians, Institute guards, and even some of the surface dwellers that have come to live and work with the Institute including Minutemen manage to hold out for a while.
What is left of the Institute leadership determines that if the more advanced synths manage to reach the surface and take control of the more mechanical synths there as well as surface synth production, it will mean the end of humanity in the Commonwealth and eventually the rest of the former US.
They order a lock down of the city on the surface which makes the more mechanical synths go into maintenance and guard mode but will prevent them from leaving the city, then together with the other survivors they destroy all access to the surface to prevent the advanced synths from getting out, but trapping themselves with the advanced synths.
The last of the Institute's leaders records what has happened as well as a warning for any outsider if one ever manages to make it to the shelter to find a way to destroy the advanced synths before their numbers become uncontrollable.
People outside of the city only notice some of the battles taking place but have no idea on what is going on until the gates in the defense walls of the city suddenly close and automated turrets come online, shooting everyone in a certain vicinity and preventing everyone else from getting near.
Trade between the city and the outside collapses in one night and the slowly advancing civilization outside is coming to a standstill.
After multiple attempts to establish contact with the people in the city fail the people on the surface realize that they must continue on their own, the people of settlements around the city are warned not to approach it.
For a while the Minutemen manage to maintain peace and stability of most of the Commonwealth around Boston, but without the support the Institute provided settlements and trade starts to collapse.
Raiders from outside the Commonwealth see opportunities while desperate people from within who have lost their livelihood turn to crime and raiding to support themselves and their families.
Even the Minutemen themselves are not immune to the collapse, and some of the more independent and opportunistic ones amongst their ranks leave the organization when they realize it is much easier to survive by raiding settlements and setting up protection rackets. The Minutemen become divided.
During this time raider settlements such as Libertalia are established.
Far from the Commonwealth, in what used to be Toronto a different society has risen up after the war.
Surviving US military members decided in the aftermath of the nuclear war that humanity could only survive under a strong hand that could provide it leadership and protection.
The armed nation of Ronto is established and settlements that rise amongst the ruins of former Toronto and around it are made to become a part of it, providing the military leadership with food production, manual labor, and a recruitment pool.
Relatively democratic in the beginning, Ronto becomes more and more totalitarian as its military become corrupt and self indulgent as they realize the power they hold over the civilian population.
In time the nation starts to expand into neighboring territories, increasing its resources and population by absorbing these of settlements and prototype states that are incapable to resist Ronto.
About a decade or more before Fallout 4 Ronto sets its eyes on the Commonwealth. Needing more resources and land to support itself its leadership decides to send an expedition force to the Commonwealth to offer its inhabitants the option to join Ronto and the protection it offers.
Some settlements accept but others recognize the totalitarian rule Ronto would impose on them and reject the offer.
Things turn violent when the Ronto Expedition leaders start to force settlements they consider useful to accept their offer to join Ronto.
Though weakened from their internal conflict, the Minutemen intervene and promise the protection of these settlements as their ancestors had done so before.
A war breaks out between the Ronto Army and the Minutemen, and after several disastrous battles the Minutemen are forced to retreat East and North to lands that are barely inhabited and still desolate.
Ronto starts to set up camps in the land they have claimed, forcing settlements in it to pay tribute, and pacifying its borders from anyone resisting Ronto's rule.
Many people have no choice but to accept Ronto dominion as without the Minutemen they are potential prey to raiders and the various mutations that plague the Commonwealth.
A relative period of stability follows in which only occasional skirmishes take place between Ronto and the Minutemen.
Ronto makes an attempt at invading and seizing the advanced city in the ruins of Boston but quickly learns the same bloody lesson the settlements around the city did decades ago. Ronto soldiers since then move around the city with a wide bow.
During this time rumors start going around that the gates of the advanced city have opened again and that some of the settlements in the Commonwealth have been visited by people from the Institute.
Even more, people have spoken to inhabitants of the city that claim to have escaped it and now want to leave the Commonwealth.
Apparently some kind of danger is forming within the city walls.
In truth the advanced synths that were trapped in the original Institute shelter have finally managed to reach the surface and have taken control of the city.
Production and development of new synths is started and synths are developed that are even closer to humanity in form and thinking.
An unexpected development takes place as synths are created that are capable to sympathize with humanity (at least they have the electronic equivalent of sympathy). They are absolutely horrified with what the previous generation has done and their plans to replace all humans with synth.
They object to these plans and when the synth leadership plans to shut them down to reprogram them to think properly these synthetics flee into the Commonwealth and assume different identities.
A large number of these synths can be tracked and captured due to an internal transmitter, others are remotely shut down or destroyed.
A handful of them however is able to shut down and remove the transmitter and hardware that has been put in them to track and control them.
The synth leadership starts to create courses to track down these renegade synths to bring them back or destroy them before they can reveal to the old humanity what their plans are. The coursers are also ordered to kill everyone the renegade synths have interacted with.
Another unexpected situation happens as newer more advanced synths are created. Synths that 'believe' that the synth shape is weak and ineffective.
They reason that the human shape is barely the most useful form to emulate and that instead synth should embrace their artificial nature and redesign themselves into form and designs more suitable for various tasks.
The conservative synths disagree on this, though they are to replace humanity they are not to modify and alter the original form.
Almost ironically the 'maximum efficiency' synths believe that the old conservative synths should be shut down to make room for the new generation and conflict breaks out between the two sides.
The maximum efficiency synths leave the city and relocate to a secondary emergency shelter; an underwater complex located in the coast waters of the Commonwealth that was originally constructed as an underwater research and habitation outpost.
I have not thought out what the background for the player would be. I think I would in general drop the whole pre war set up as it barely contributes to the campaign and seems to be more designed as overdone dramatic porn as the whole father setup was in Fallout 3.
More on this later.
