I don't have any problem with the factions being "grey", but what bugs me is that if you work with all the factions more or less equally, you can gain a pretty good reputation with all of them. (other than the legion of course, and you can keep neutral with them for a long time). Most of the factions aren't really at odds with each other, perhaps not in full agreement, but not shooting on sight either. I could easily imagine the NCR, BoS, and House coming to an agreement very similar to the one that exists, and teaming up against the legion. Especially with the Courier keeping the diplomacy open. After I completed the BoS missions, i really had the impression that they liked me a lot, and would've at least listend to waht i had to say. Same with NCR. I would love to see a mod that allowed you to convince House that the brotherhood was no threat to him, and back that up by convincing the brotherhood to leave House in peace. The NCR could still Govern the area, allowing House to keep control of the strip as long as he behaved. They could continue to support the followers and thier good works, and even allow the brotherhood free reign out in the wastes. The courier would be in a fantastic position to negotiate the treaty, and all the factions would be able to do thier thing once the legion was put down. Seems to me to be the best way to maintain stability in the region, and cause the least collateral damage.
