Well, of course you wouldn't notice this considering the very area you play the game is under the Legions assault. They're not going to have caravans and stuff around in their enemy's own territory are they? When Romans fought they fought with full force at any cost, thats why it makes sense that you wouldn't see anything good from them as long as they were fighting where you happened to live.
It makes sense, but it meant players weren't given any incentive to actually join the Legion. The path I was expecting the game to take was the player starting out thinking the NCR are the good guys and Legion bad, but as the game progressed you found out the NCR were very bloodthirsty and self serving and the Legion were actually totally capable of rebuilding society. It didn't go like that at all. Instead you find out that the NCR are just stretched too thin and the Legion are boring as hell.
I was particularly disappointed by Bitter Springs. Constant allusions to it by different characters, big thing in the prequel comic, and instead it's just 'Oh no the NCR killed an entire town LOOK LOOK WE DID MORAL AMBIGUITY'.
