@RhockoHarrison I suppose that's true but the way I see it even an NCR that fractures and collapses will leave behind the bones of higher modes of organization and production for the people of the West coast to try again (not taking in accoint the TV show butchery)
@RhockoHarrison Yes Man is there as a wild card and any good ending requires assuming a Yes Man Courier dictatorship to even function
The only real issue with the NCR ending is that it encourages all the bad tendencies of the republic but its by far the most stable ending
@RhockoHarrison The Legion just exists as a vehicle for Caesar to coup the NCR, whatever civilization they carved out seems accidental and wholly dysfunctional if they fail to win at the Dam.
