I was saying the exact same thing, but with less aggression. The Yes Man option could possibly have been the most in-depth option, but due to time constraints (or whatever other reason), it was just a re-done Mr. House. It could have been developed to include forming actual long-term alliances (as opposed to "I help you with a problem, you send some cannon fodder to help at the Dam"). I would have like to see the BoS, or Boomers (maybe even both, as it should be possible with 100 speech) spreading out in the Wasteland, occupying positions like Helios One, which both could benefit from. also, after killing Mr. House, you should start getting access to his treasury. Evil karma players can just hoard it, while good karma players can donate it to the Followers. This could lead to interesting possibilities, where you see more Followers personnel in Freeside, and less crime. the lazy players could just deal with Vegas itself, but the resulting chaotic wasteland should be reflected in the ending slides.
I actually like some of that, the independant root is really because you want to be either a
liberator or a greedy bastard. I have to disagree on the Boomers though, they haven't left the same few square acres of land in 50 years and had ample oppertuinty to do so before the factions arrived; they want to take in the wasteland
very slowly and, from some dialouge, it can even be said that the children are more crazy than the elders.
"The youngsters wanted to shell a real target..."
The BoS do occupy some Helios ONE (bastards) in some endings, but really their numbers are shot to pieces and I don't think that reinforcements either cannot or are not willing to break through strong NCR lines.
