They never said NCR wasn't the biggest one. Everyone knows they got the biggest population.
As I said, I don't care that much for how many camps they have but that they have a crapload more quests than CL.
Joining NCR must be really fun seeing as how one get's a lot of quests.
Joining CL on the other hand was frustrating and confusing.
Don't care that they only have like (from what I've seen) 4 camps while NCR has like two dozen.
I care that I never get any quests from them.
