I talk a lot about idealism vs. pragmatism, and I think the NCR vs. Ky-SAR’s Legion would have been a great place to do this. Have the NCR dedicated to the ideals of democracy and bureaucracy to a fault. “Oh, your town is being raided nightly by fiends? We’ll table a motion at the next meeting to form a fiend oversight sub-committee and investigate possible solutions to this fiend issue.” At the other extreme would be the Legion. “The fiends are going to wipe you out. Pledge to pay us exorbitant taxes, and we will place your town under the protection of the Legion. We might need to take some of the men to serve in the legion and a few of the women for other stuff. Basically, sell yourselves to us, and we’ll see to it you survive.”
The game came close to this, but the Legion is just a bit too buffoonish to be a proper foil. They aren’t just callous. They’re bloodthirsty, incompetent, short-sighted, and ignorant.
And they dress like clowns.
