@mr. bazooka.
I think I didn't make myself clear. I meant that if the Colonel Autumn would leave the enclave in shame of his failior and well... start a new life as a deadbeat/gambler/playboy/caesars made man. (or maybe i am just trying to force myself to think that fo3 is canon)
Other things would be that BoS would go back to "underground" faction that sees and hears everything but is not seen or heard.
And this the way things should be:
Gambling->Organized crime->Mafia=cool suits, tommy guns and really colorful dialogs with psychopath "scarface"-like made mans and with fat tonys.
And maybe the most essential on my wishlist(if the basic "better storytelling" "no aliens" and "f'**k you bethesda" are not count) more stories involved into the places, i don't want them to be like "oh, another hidden military base" go in, kill sentry bots, loot everything, go out. Many places in fo3 were like "oh, nice idea" and five minutes later "duhh". And EVERY building in the dc had almost the same interior. Sulky corridors, muties, terminal somewhere.
Ps. how about fat robot-Elvis?
Edit: "The NCR was fighting hard against the Brotherhood of Steel for Hoover Dam. The NCR has won this battle, barely." -So long for the underground hi-tech BoS not messing up with politics and such...
