In Fallout New Vegas, which one of the factions did you guys join up with and end the game with and why?
I joined up with the NCR, after downloading the NCR mod so I could actually join the NCR ranks. I mostly joined the NCR because it was the most militaristic to me, and I enjoyed the world war 1/2 style uniforms that they offer, and they're great for roleplaying.

Yes man, NCR, NCR, and Tried to go with BHoS but realize I couldn't get the ending with them so I went NCR again.

so In total I beat it 4 times now.

I joined up with the legion only to hate them and ever since have always done the yes man questline.

NCR

Although they have ridiculous Tax amounts, They really are trying their best to keep Law and Order on the Wasteland despite the Heavy Taxing

I can't stand the legion, never mind the crucifixions, I just couldn't handle being called "profligate" by some bloke in football pads. However I think the NCR would fall apart after not too long on their own so it's got to be yes man all the way since House is a prick too...

No one. I don't like anyone faction.

NCR. Though I liked the Brotherhood of Steel so I managed to broker peace between them.

I joined Yes Man, because it seems like the lesser of the other three evils.

In Mr.House's ending, there are heavy taxes on those wanting to enter the strip, The NCR heavily taxes Goodsprings and the surrounding area of the Mojave (To probably pay off the amount of money they spent on the war.) 

I didn't want to go with a society that emulated the Roman Empire, and I didn't want the same old world government that caused the war in the first place.

Yes Man is the best choice, because you (The Player) secures New Vegas's independence, and the town of Goodsprings thrives.

The NCR is also very bureaucratic, but they have a much better chain of command than Caesar's Legion, which easily falls apart if Caesar or Legate Lanius dies..  

The Legion relies on brute strength, Slavery and intimidation tactics.

They don't properly educate their soldiers, many are taught to live a life of servitude towards the legion, and probably wouldn't fare well on their own..

the NCR on the other hand, would have the funds to educate their citizens..

That's where Yes Man kind of falls short, the courier just leaves after securing New Vegas's Independence, it's up to the people of New Vegas as to what will happen, which can either be a good or bad thing..

Me too
Always Yes Man. Only sometimes i tryed with the NCR or House but the best is Yes Man

Mr. House if you're for the common good of humanity.

Indeed some individual things are better with Yes Man's ending, but House is simply too valuable to the human race to kill, just so you can have less taxes or have a town of 10 people thrive.

I always side with the NCR as Raz puts it, "At least the badasses with the top shelf guns are on my side".

I kill both then side with deathclaws and do what i want.....

I like to get companions and make my own little faction within the NCR named the NCR Contractors, hence my title. I basically side with the NCR just because I like their history and uniforms. I also just don't feel strongly about caesar.

Brotherhood and Ncr. Get them to ally with each other and then I would roll-stomp the legion back into Arizona with my T-51b and Gatling lasers

Myself, because I don't trust the NCR and the Legion are slaver scum that is simply and organized scum

No gods... No masters... I'm lone shooter

No masters either I go it alone. Trade with all submit to non

The only one that I have tried is the Yes Man one. Maybe I'll try a different one someday.

I may have answered this on another thread but I'll say it again...

The first faction I helped was NCR. Can't say I would join them absolutely, though I was on a ride with these guys for a little while until they somewhat turned traitor on me and my people(Mod related). They don't respect me and thus their alliances with my faction was short-lived. Thanks to the convincing evidence from the outspoken exploits of NCR by other people in the game who were victim to it. Sure, NCR may have a tough job but they take things beyond the limit that I feel are too excessive, and I can't trust them to govern for New Vegas or any other region.

However, I finished the game with the second joined faction Yes Man. It was at this point I decided to give NCR the finger and split paths. Thus is what happens when you push people around, even your allies, they are bound to switch sides. Yes Man then became my only choice of ending the game until later, some changes were made in my decisions.

I then decided I wanted to cut off all the five fingers of NCR, basically their VIP key people and I wanted to do it all simultaneously, even take out President Kimball, but this likely wasn't possible without mods and certainly without climbing into the ranks of the third faction, Caesar's Legion. I have no vow or allegiance to the Legion itself, though I only infiltrated the Legion just to kill off NCR's key people, and then backstab and betray Caesar himself when he wasn't looking. Of course, I would never agree to the laws of slavery. After all, I was on a mission to destroy both, by acting as the Legion's inner poison, helping them unwillingly...

But then I am also convinced by DVAted and other people that Mr. House wasn't exactly a tyrant. Sure, he has a robot army to guard New Vegas with, but then again it's better to have a human mind in control of the machines rather than let the AI corrupt itself. Thus, he is a man of a vast understanding in science and the technology factor. Not only that, but I am also convinced he does have logic at least. So at this rate I feel compelled to at least grant mercy to Mr. House every playthrough, sure Yes Man is my second choice if House fucks up, but enough to say for my experiences in New Vegas, I played every single ending. I have to say not either the NCR, the Legion or the Independent ending was satisfying enough, even though Mr. House would certainly do a better job giving shelter to the inhabitants of New Vegas if I were to end the game with him.

I joined the NCR,because they're in need of help,mostly because they're preparing a war with the legion,and the legion has more allies.
