Yeah fonv seems a little ncr biased with legion and house getting screwed quest wise
.
With the Legion I can see a good case for having more quests, since they're trying to destabilize an entire region at once and can probably use some help with doing so, however in House's case there really isn't anything else he needs you to do, beyond retrieving the Chip so he can upgrade the Securitrons and getting the ones under the Fort up and running, so further quests wouldn't really make sense.
If anything, what I've seen over multiple runs has me thinking that the NCR has
too many quests, because their incompetence has been grossly overdone for the player's benefit. For example: even someone as apparently clueless as Kimball is would have long since realized that Oliver is not fit for a major command and replaced him with either Hanlon, Hsu, or Moore, with the direct result of removing almost half the quests as they involve things that no commander worth his or her rank would
ever leave untended*.
*I am aware that the NCR is overextending itself by being in the Mojave in the first place, but that's a pretty (even
very, in some cases) thin cover for the situations of some NCR outposts.
