The NCR doesn't have the best ending out of all of them if you do it right.
[sub]All factions are flawed, but that's the point. Also the NCR ending is the only one that will actually give the best ending for your companions.[/sub]
I don't want to play New Vegas now...great thing that I can because I have nothing else to do. T.T
I also hate New Vegas because it follows the Fallout Lore that was in in Fallout 1, 2, and Tactics.
