Alright, it's obvious that all of the factions in the game represent a type of social, political, or economic type of government. Even the developers were going for that as they said so in the faction trailer. Let's get the obvious ones out of the way

NCR - Basically Pre-War America. It has a Congress, it has a President, and it has all of the corruption that comes with it.

Caesar's Legion - Has all of the oppression of a totalitarian dictatorship yet has little to no crime, very strong army, and has nothing to impede any good things the dictator wishes to do.

Mr. House - Benevolent dictatorship. Has all of the perks of a dictatorship while all of the freedom of a democracy. However, Mr. House has a severe case of Old World Blues. Don't know what that stands for...

Yes Man - ANARCHY!!

Kay.

Okay so which do u like

The House allways wins.

Except when it Goes Bust.
