The NCR taking over is a flawed solution, a sort of mixed good-ish ending with some unfortunate consequences. NCR's basically a criticism about elements of the modern U.S. It's got a lot of corruption and government nonsense that slows things down, makes plans to help people or build society less effective or counterproductive, they've got an arrogance and controlling attitude toward the territory it wants to control, etc. I remember at least a couple things going significantly downhill, going the NCR route. It is one of the options, though. And I think it's flaws actually make it a better ending writing-wise.[/quote]

What you do in the Wasteland can help solve the NCR's problems back home, on top of the NCR serving to defend and develop the Wasteland. Persecuting the Crimson Caravan Company, for instance, via Cas' quest-line.
