look I know it would never happen but what you guys think would happen. I think it would be a unstoppable force to be wrecked with.

As you said, it could never happen given the vast differences between the cultures of the groups. But in a purely hypothetical situation, I think we'd end up with something similar to the 3 branches of the US Government, but only a Senate and an Executive, making something similar to the Roman Republic (Likely without slavery of course).

Militarily, I'm sure there'd be some mixing, Rangers with Centurions for example.

What if the Allies joined forces with the Axis in WW2? Or if the Union joined forces with the Confederates during the Civil War? That would've made those wars so much more epic! lol

If they did join forces I think each side would get quite a few deserters because they didn't want to work with members from the other group, also it would be challenging when the group leaders sit down to discuss what is allowed and what isn't.
But if the two group join and govern the area together they might become too powerful which might cause civilians to rise and revolt against their leaders, which could then lead to battles or a war

This is like what drunk men discuss when they are drunk and is a good thing.

First of question we must answer is HOW they are going to become allies.

One possibility could be because of a new threat

SPOILERS

Spoiler:

Then they eliminate the threat and after that, they end the truce.

But what if they didn't? What happens next?

NCR and The Legion would have to discuss stuff about slavery and whatever the NCR thinks the Legion is doing "wrong". Then the Legion would probably enslave the NCR and rename the NCR to the New California Legion. Because they can. Then the Legion would continue what they are doing.

But yes, I seriously think that if they ally, the legion would just go and back stab the NCR.

I think that you think in absolutes. Even if NCR and Legion were to cooperate due to a new threat (which I think wouldn't happen because Legion are pompous asses and they wouldn't admit they need help) they wouldn't become too merged (they would never trust each other) for Legion to "enslave" NCR. I think that after defeating their mutual enemy the war would simply continue.

If the Union and Confederates joined together there would be no civil war and or it would end just like that lol.

As for the main topic of course it would never happen, they have completely different ideologies. Now what could seem plausible is one of the two factions subjugates the other. So one forces the other to become a military ally rather than wiping each other out. That would however cause a whole regime change in who runs each faction so president Kimball and the other NCR top leaders would be ousted, killed, or imprisoned because they are hardline supporters of the NCR and its values. Same goes for Caesar,and his top leaders, they would never change what they have been doing for years which is enslaving, torturing and conquering tribes ect. One who would rather die than be subjugated is Lanius , he will never join with the NCR period. Would be an odd pairing we have on one hand the upholders of democracy in the post war world and the totalitarian regime on the other. Only time that i could see them joining together is if there was a even greater threat than themselves.

This would make an interesting mod, like your teleported to an alternate dimension where the legion and NCR have united under one leadership. And they carry on all the worst triats of the factions in your world.
They unite under the cruel hand of, the courier. Thats right courier six (or at least the evil version of courier six. Possibility dictates it doesnt have to be your character)
Point is The NCL(New California Legion) are cruel monsters and now its up to the man/women to find the scientist in this demension that sent him here and get the hell out before they get themselves killed.

But as is said, the union would never ever happen as they are too different. At the same time, IF they could agree on a situation where the legion patrol the roads, and the NCR protecting the larger settlements, realistically you could have a very safe land.

If both are allies, then all hell gone loose

Well in that case we wouldn't have the wonderful game of Fallout: New Vegas, and I would have to settle with Fallout: 3. Which would make me very, very sad.

In that case game wise though, what faction would be able to contest them? how would they be able to merge their creative differences of slavery and freedom? Questions you have to ask yourself...It just wouldn't work, and for sure wouldn't last.

I believe the only way that would happen is if the Legion conquered the NCR or simply annexed them and just fused the NCR's army with the Legion. I do believe though that the Legion would become to thinned out to keep their territory. They were spreading to quickly and would crumble under their own weight once Caesar died.

NCR and Legion would only be allies if aliens invaded Earth.

If somehow they did become allies I feel they would go east and attempt to conquer the midwestern Brotherhood of Steel

Never, there backgrounds are completely opposite , the legion are literally savages , and the ncr is actually trying to help out somewhat.

"Women of the world take over, 'cause if you don't the world will come to an end and it won't take long."

As you said this couldn't happen, reasons being that their approach and views on disaplin, power and how to handle people are just to vastly different. NCR train their people to become strong soldiers and if they make a mistake, are suspended or put to a worse post. Legion also train their soldiers but if they make a mistake, death is normally the punishment. Take Joshua graham for example, made a mistake and was burnt and thrown off the Grand Canyon. If they were allies and that happened a massive dispute would surely happen.
In leadership legion has one ruler who rules with all power and is very harsh, in NCR it is more of a diplomacy. When civillians are bad e.g. Powder gangers the legion crucifys them where NCR in prisons them. The views on this are just to great and vast for an alliance to ever happen.
Not to mention the hate soldier of each army has for each other.
And cesar is also dead

to honest no, the ncr are corrupted but good folks and the legion arent what they say the legion is like the NCR corrupted too. NCR killed an entire village at bittersprings, the legion kill and enslave the khans. I tried bring alliance with the khans and ncr, but theyre were upset. I choose yes man to take over vegas or mr.house.

I'm assuming it would looks something like this:

Spoiler:

Nah. I don't think they ever would. The only way I could ever see it happening would be what TixIssence56 said and that they would only "unite" if something was going to eliminate both of the factions, although very very unlikely. Even if they would unite, I still feel like they'd feud and fight because their ideals are completely different. The Legion seeks to enslave everyone because they are weak and the NCR want to protect everyone for the same reason. That's what I think anyway.

Good question!

I must admit that I do not have a large knowledge of lore on the NCR or the Legion. Only what I gather from the endgame cinematics.
