Depending on how you play it with House and Yes Man you might have to fight both NCR and Legion though.
And with NPC dialogue, what do you expect?
The game was designed in favor to NCR territory.
If they had had a map node system then we could easily have had a city from Arizona or some other pro-Legion place and we'd have more to go on.
But due to this [censored] awful crap sandbox map the game had to be sided on one side of the river and NCR's side won due to including House and the actual "Vegas".
So I would rather blame it on that Obsidian had to work with a crappy sandbox map and barely had 2 years to make the game than to say that they were "designed as the baddies."
Regardless of the initial plan, they still come out as the baddies; most NPCs range from dislike to fear of them and all we see from them are atrocities. That may have been caused by design limitations, but it's what happened.
Those atrocities as you'd call them is just good ol' psychological warfare, and it's definitely demoralizing NCR troops, so nothing wrong there. While you never actually *see* anything good from the Legion, do keep in mind that all you see is their war camps.
I don't buy any of this "they're simply evil" nonsense, because when it comes down to it it's all about personal perspective.
Look, no offense, but nobody took this argument out of context; this statement is startlingly inaccurate
in context. You are literally saying that crucifixion of entire town populations, forced slavery and abuse of women, etc, are just "good ol'" (to use your exact words) terror tactics.
Yes, they are "good ol'" terror tactics. But, you see, the thing about
terror tactics? They're supposed to be overly brutal and horrifying to, y'know, cause terror. Legion's methods of enforcing law are most certainly evil; whether you believe the ends justify the means is another thing, but arguing that what they do is in of itself anything but evil is simply nonsensical.
Human crucifixion simply for being "immoral" can't be called anything but an atrocity, as far as I'm concerned. It's horrific, brutal, and entirely disproportional.
