Hmm... I don't want to kill The BOS! But House may be better for overall stability. Oh well, I guess.
The thing about Mr. House's ending is, you have to appreciate things from the big picture. But with me, I'm a mix of white knight. I see it as House helping humanity on the big picture, and I'm helping it pieces at a time. I take the time to donate to max capacity the meds the Followers need. I save any NCR troop I find. etc.
Mr. House runs Vegas as a business, which for all intents and purposes, it has always been a business. Plus, NCR is over bloated and spread to thin, and the Legion, well, they're savage as they come. But House has no want for expanding. I see it as NCR continues to do it's thing, and Mr. House will rebuild Vegas to Pre-War glory. It's a best of both worlds situation in my book.
Edit: @Last- It wasn't a slide, the Followers denounce NCR because they see NCR as inefficient, the Followers are in it for the people, the NCR is in it for glory and money. They both do the same thing, but for opposite reasons, and that's why they don't get along. It made me glad I'm a House supporter when some NCR dike called Arcade an 'Anarchic Cultist'.
