The NCR is expanding and taking over every community it finds, which is very imperialistic. They also did the whole massacre at Bittersprings. There are a whole bunch of minor things as well that disillusioned me with the NCR, even though I helped create it in FO1 and 2.
Caesar's Legion is surprisingly less evil than I thought. Yes, Caesar is enslaving entire populations, but he's doing it with the intention of bringing civilization back to the wastelands. He also instills honor and loyalty in his legion, even though women are no more than property. Many modern countries went through painful growth as the Legion is going through, and Caesar knows this. For all its faults, the Legion has many redeeming qualities.
Mr House... what can I say about him.
The Brotherhood has always been extremely secretive and xenophobic. Yes, they're the heroes in FO1, 3, tactics, and BoS, but it seems like every game you deal mostly with splinter factions with radical ideas rather than the mainstream Brotherhood, as represented by the Head Paladin in FO:NV.
The Great Khans make drugs and sell it. They're criminals that have suffered a terrible tragedy and are being pushed around by the Legion and NCR. I felt sympathy for them after thinking they were no better than the Jackals and Vipers for a better part of the game. But still, I can't quite get behind them.
The Boomers are awesome, but instead of helping out the people of the Mojave, they shell them with howitzers and missile launchers. Yeah... no.
The State of Utobitha is supposed to be a haven for super mutants and nightkin, and they warn humans to stay away due to the radiation... but they shoot on sight.
The Powder Gangers were put through hell in a NCR correctional facility, but most of them probably deserved it.
The Crimson Caravan were harmless at first, until I unraveled their secret plans. A greedy corporation.
The Kings are amazingly funny, but honestly they seem like gangsters more than anything. The King himself is a decent guy I guess.
So in the end, for me, besides the Followers of the Apocalypse and Jacobstown, I couldn't find a single faction I actually believed in. Thus, I felt pretty amazing when I found out the last quest in the Yes Man series is called "No Gods, No Masters." If no one else has a worthy vision for the Mojave, I'll impose my own. What are your thoughts? Do you believe in a faction?
