Again, 90% of games let you ask things that should be public knowledge. Some even lampshade this calling you stupid for asking such a thing.
Singling out New Vegas out for this seems misguided to me.
Because the player has to be told these things, and an info-dump at the beginning is... dissuading, particularly to modern gamers. That's kinda why so many stories, even books and movies, star protagonists with amnesia. It's a trope, but it's also super useful for catching up the players/viewers.
Here they had a perfect excuse for amnesia. In fact I swear the dialogue, at many points, implies that the character doesn't remember things. But nope, pointless word of god. Nah... rejecting that.
There is no real civilians in the Legion.
From what I hear there are. They just never got around to adding it to the game.
Well there are all the slaves...
The tribes are off to the east, what we see is just a military camp. For what it's worth, Cassidy sorta indicates that things aren't so bad for traders out there. Which seems to clash with what the Legion ended up being, due to rushed development.
I am physically unable to play an evil courier.
Or evil lone wanderer.
Or an evil pretty much anything.
Courier especially, because there are so many fucking douchebags in the Mojave who need their shit beaten in.
I couldn't be too evil in Fallout 2 either because it mostly meant slaughtering useful NPCs. Or working for the crime lords I guess, but they were dicks and I was already good from fighting raiders.
But in NV I was pretty much neutral. I had strong feelings about some of the factions, because they were each interesting in their own ways, and dealt with them appropriately.
(Exception: I held back from slaughtering the Boomers. It's not their fault their air field was so fricken huge to walk across... Also my brother likes them a lot. Even though they're dicks who shelled me.)
(The Khans can screw right off though)
You're kind of really desperately grasping for an excuse here, from what I'm getting. It's fine to just not like the plot...
I don't think it's about that anymore, it's just really stupid that a dev would claim the courier doesn't have amnesia. When everything in-game strongly indicates that the courier has amnesia.
