I'm pretty much at the end of the game but I'm not really digging what I've had to do to get to this point.

Is there any way to Ally Mr House with both the NCR and the Brotherhood of Steel? I'd rather keep House alive and make an Alliance with him and the BoS & NCR, anyone know if this can be done, has anyone done it?

You cannot ally House and the NCR. And House won't suffer the Brotherhood to live.

House and NCR are diametrically opposed. They both want complete control of Vegas, an alliance is impossible.

Thanx guys A bit of a let down though, I wanted them all plus the Boomers and the Enclave Re. to Ally, not that I can get the Enclave Re. Quest to Activate, I did most of the Trust Markers for this guy (can't remember his name right now) at the old Mormon Fort, saved President Kimball and I've popped back (many times) and still can't get that bleedin dialogue to open up, whats going on I've practically finished the game, with does it take,? So theres no option for I want to happen in the game, Great! Little disappointing all the same.
