So, I was going to go down the House Always Wins questline, first mission up is convincing the Boomers to support house. Had a look at the quest guide on The Vault and it turns out that after the Boomers you are convincing the Omertas, and then... you wipe out the Brotherhood. Wha?! I thought House was the morally grey option rather than good or evil, but killing everyone in the Brotherhood bunker is going a bit too far for my morally dubious character. And Veronica sure won't like it!
Fortunately I discovered this before I actually went and persuaded the Boomers to support House... but what if I had already done it? And persuade the Omertas? What would happen if I then went and killed House? Could I still side with NCR or go independent with Yes Man, even after persuading two factions to support House?
I know! I stood in front of Mr. House, a member of BoS, in full power armor.
There were no choices - so that killed the House ending for me.
Actually it is a slow process of elimination.
First Caesar becomes un-doable, 3 paths remain.
Then I was forced to cause Mr. House's retirement - 2 paths remain.
I worked for YesMan one time, right from the get-go...
But another time I worked for NCR right up until the final battle, after saving their President for them, then switched to YesMan (very different experience).
When I then informed YesMan that the BoS were already comitted to serve alongside the NCR - he was horrified and said "they will both want me dead". :shrug:
I wonder if it's possible to support the NCR until The BoS comes onboard - THEN switch to Mr. House? I'm gonna try that again (but I think House gets mighty upset about my NCR work, whereas YesMan not so much).
But there's no way the BoS is gonna be taken out by me - that's a breach of trust that House is just not worthy of. Not gonna happen.
Maybe in doing Caesar's ending, heheh, okay... but not for Mr. House.
