New Arroyo also can easily ally with both the Shi Empire and NCR, together with weaker neighbors too like Redding, Broken Hills and Pioneer Alliance(Klamath and Modoc), making a very strong bloc more than capable of defeating Enclave together, but the AI obviously doesn't take advantage of such detail. I tried playing with New Arroyo first, and did exactly this. Lets say that by endgame New Arroyo annexed all hostile countries to it, had 90% of North and Central America under either its or allies control and just made an alliance with the BROtherhood of Diversity. In other words the game was won already.
Also Former USA is much more powerful than what the inept handling of it by the AI suggests. I've played with it and crushing the Dark Cathedral was not really difficult thanks to the fact they start with a single armored division, and most units in early game have 0 hard attack and much lower Org. than the few armors. And Caesar's Legion quickly fell afterwards too.
(probably two Powered Scout brigades, like the Enclave)
They actually start with two Powered Marines batallions capped at 40 maximum strength, that are much stronger than powered scouts. Also, speaking about powered marines, one of the coolest attachments to units are actual jetpacks in late game.
The very late game implies the beginning of an actual reconstruction of a futuristic civilization with eventually power armors becoming standard body armor for the armies and the restart of a proper industrial society and thus would no longer feel like Fallout in style, but more like, say, the Earth 2140 RTS which happens in a post-nuclear world, but one where highly advanced technology and major powers still exist.
=============================
One war to define the future of the Wastelands
The enemy shall have no peace. Rock Springs shall be retaken at any cost, and then, as soon as this brutal war of attrition for it is over, everything will be ready for subjugating these vile Vault City scums. The glory of the Hivemind will know no boundaries.
The army continues to grow exponentionally, and although the war has reached a stalemate, sooner or later Winter shall be over, and things will then definitively turn in favor of the Under-Nation. The enemy shall never have peace, dignity or sovereignty again.
They fight bravely to ensure their victory shall be worth, but unfortunately they are too exhausted by the cold to succeed, and thus Vault City once agains succeed at advancing against Rock Springs, and once again everything will start over again.
Suffering heavy losses, their ambitions crushed and Anaconda lost, Vault City desperatedly begged for peace, attempting to solve their issues with the rats through diplomacy after attacking them without any real justification. There was fear in the eyes of the diplomat who made the offer, eyes which know are part of a creepy collection of body parts the Founder mantains to remind himself of those who were conquered.
Unfortunately the Ghouls of Gecko once again have dared to rise against the Hivemind. They shall pay dearly, very dearly for this. The executioners and torturers along the Under-Nation were having new ideas to implement, to make examples of. They would make a new form of torture by using the Forced Evolutionary Virus to transform ghouls into organic trees and torture them at their new, miserable existence.
Where did I see this before again?
Slowly the reintroduction of scavenged pre-war and new technologies were turning the military of the Under-Nation into an equal to the militaries of the early 21st century. Proper equipment for soldiers was already being researched, and soon the glorious army would deserve being called a professional military force proper, equipped with real uniforms and body armor instead of how it currently looks like. It is ironic that the rats are forced to use men as their puppets, unable to conquer on their own. Meanwhile, Pinky and Brain began to research the introduction and adaptation of Pre War computers for rats to use.
The year of 2249 begins with a second offensive against the Vault City occupation of Rock Springs, to show them that the will not give up until Vault City falls and Lynette becomes their bitch. It was a matter of honor to destroy Vault City and subjugate their self-centered citizens. Once again Vault City strategists foolishly send too few of their men to hold Rock Springs.
And another thing happens in this new year together with a new victorious advance against Rock Springs, which may not succeed at holding it, however. The Rat Council becomes stronger through the purest form of natural selection. The strongest and smartest, as always, prevail. The rats grow smarter with every new generation, and this may be the beginning of a new age in Earth, an age where Dinosaurs and humans will be alike and a new species shall rule the world.
In their foolishness to declare war against Caesar's Legion while fighting the God Republic of Texas, the Tribals of the southeast Kwanzania are finally subjugated by the forces of kingcomrade and the Trannies of Battle under the leadership of Kaiserin and forced to convert to their fanatical and fundamentalist Church. The God Republic of Texas thus becomes a major power(Now I think I should have included it in the poll as the "kingcomrade" option, but then it would be too predictable the result of the poll).
The highly intelligent but physically frail and mostly blind rat that the Founder has chosen to secretly protect and support becomes a great genius within the Under-Nation. Known as cross-eyes, he learns of new methods to drastically raise the life expectancy of rats and manboons alike, becoming a very valuable asset which shall soon begin to research advanced medicinal technologies.
Tired of the boasting from the remnants of the Enclave in Navarro and Alaska, the Shi Empire decides to take actions to crush what they consider right now to be the greatest threat to their sovereignty. Kwanzania has never seen wars waged at such scaled within its territory since the Amerikwan Civil War times, wars that shall definitively have a major involvement in defining the future of this land.
The feral and brain-eating ghouls never were completely defeated. Only driven back, but their legions proved too formidable to be properly exterminated by the existing wasteland armies. Even the BROtherhood of Diversity was having difficulties against such a foe, in spite of their access to advanced technologies. The region around the post-ITZ Cleveland once again hosted another ITZ as it was taken over by the Zombie ITZ.
Meanwhile, acknowledging the threat of the theocratic power next to them that viewed them as heathens and scum of the Earth to be cleansed with blessed fires and burned at stakes, the slavers of Caesar's Legion decided to preemptively declare war against the God Republic of Texas in wake of their recent conquest of the Manitou Tribes.
It is the 23rd Century, and in the Grim Darkness of the Wastelands, there is only War. War never Changes.
Separated by distance and ideology from the main Brotherhood forces, the minority was free to forge a new BROtherhood of Steel, one that reflected the ideals they strived for all along. However, one's future in the Wasteland is never certain, for a New Power has awakened, also bent on making this land its own.
Life in the Brotherhood is about to change...
