The lower left is taking over for myself, right? That’s me. That’s my favorite way to finish NV. Pretty sure that’s the real, canon ending since it’s the one that is closest to the canonized endings for 1 and 2. The “everyone who isn’t a total piece of shit gets what they want” ending.
Then again, maybe the devs actually consider the NCR the good guys, given how they have grown from Shady Sands from FO1 into what they are now. I still don’t like 'em. We don’t need to make things the way they were before the bombs fell, which is what they feel like. All that does is lead to the same shit.
