Well, i know this sounds wierd but i was wondering, what if anything does Ulysses, the character from Lonesome Road, represent? Does he represent anything at all? My guess is the old world, but i also heard someone say what he represents could also be considered his meaning, but i am not too sure.

Can anyone tell me?

I think he represents the opposite, he see's the NCR and Legion as the left overs of the old world and he wants to reshape it into a new world... by destroying what's left of the old world with what destroyed the old world(nukes). if that makes any sense.

He wants everyone to be united under one symbol, which is why he's into the Old World flag- it's the last symbol that united all of America. He thought the Legion might be the ones to do it, but he now thinks that because the Legion is based on war it won't be able to function without an enemy.

"Ulysses = The Courier (Independent Vegas)

Throughout your travels through the Mojave, what question is probably on your mind?

"What is the right thing to do?"
"What do I believe in/what do I support?"

What is the Independent route? Arguably, of all of the choices, it's the one with the least amount of personal profit. There was a time when we thought Indy meant you're the new ruler, but the developers have since let us know that belief is false. Caesar offers you gold, the NCR offers you bribes and House offers you a life of luxury, but Indy offers you nothing. Indy is a choice that's made solely because you believe in it....or, out of ignorance you believe it'll profit you, and your ignorance costs lives.
The independent Courier is, in a sense, "finding himself." And Ulysses? Ulysses is doing exactly the same. While you're struggling with the conundrum of "war....war never changes. But why?" so is Ulysses. Both of you are searching for something to believe in. The independent Courier has to make decisions purely for himself. These aren't decisions being made for you; no, you have to get to know each nation and decide if you agree with it's existence and philosophies or not. You struggle to determine if Caesar/Elijah's desire for control is justified or not, as does Ulysses. You struggle to determine if the NCR's/Graham's compromising themselves down for more practical results is justified or not, just like Ulysses. You struggle to determine if House/the Think Tank's more selfish outlook on things in a sort of attitude that there IS no solution so you might as well enjoy life and take what you can for yourself is justified or not, and so does Ulysses.
Ulysses eventually decides that he will compromise himself down and take a practical solution in attempt to control the outcome of the Mojave SOMEWHAT, but his interests are purely for the sake of humanity, not selfish ones. Ulysses hates someone who doesn't put thought into their actions, because for an independent path, thought is definitely neccesary or people will die. The conundrum is that Ulysses is still opting to kill people, in a belief that it will save people, similar to how an Indy Courier may opt to destroy the Brotherhood in the Mojave; such is the the struggle of Indy and Ulysses.

And what becomes of Ulysses? What becomes of Indy Vegas?

Simple.

With a little respect for your fellow man and another nation, people live on. Without that respect, people die. Ulysses challenges your beliefs, and if he doesn't feel they're justified, he loses repesct for you. So much so that he declares you and the nation you support "wrong" and opts to kill you. Even if you win the fight, someone has died. If you show him your beliefs are justified, he gains respect for you and the nation you support, opting to let you and that nation live on. He decides to give them a chance, and even fights alongside you in the face of adversity, much like two nations might learn to fight alongside each other. The Courier essentially does this with Independent Vegas. He visits each nation and demands justification. If he receives some, the nation is probably allowed to survive. If he doesn't, he'll likely crush that nation."
