Let's say you're Robert House and you have a body again and YOU can act as the Courier. You happen across the Kings-NCR dilemma in Freeside and you can choose how to manipulate the situation.
Which would he choose? He could either manipulate the Kings so that they hate the NCR and remain more loyal to Vegas, making them of potential use in the future...
Or he could manipulate them to work with the NCR, giving him an excuse to wipe them out and take over Freeside for himself?
That's what inspired this thread. House focuses on progress and profit and nothing but. The why's and how's do not matter. But from a business perspective, I can't quite decide if the Kings are better gone or as potential "employees." Or if it's better to manipulate the NCR and Legion for profit, or to bomb them both and revise the business plan entirely to adjust for a new "market" where he clearly has total control.
In the end I think it's about being objective. I personally would decide to destroy the Kings as what they stand for could potentially threaten the House regime, whereas I'd opt to not bomb the NCR because the NCR surely has resources that could be useful. The Legion on the other hand? Again, good question. By the time House has won, the Legion is of little threat at that point. They no longer function as a threat to the NCR, and besides, if done correctly the people of the NCR would never support a re-invasion, according to House. This eliminates the Legion's use entirely, and the Legion is EXTREMELY unlikely to somehow work with or benefit the Strip at all, since the Legion citizens have been taught to work towards a common goal and a higher purpose; something the Strip clearly does NOT stand for.
But does that mean they should be rid of entirely??
The Legion? Yes.
I would go in this order for Mr. House
1. Nuke Legion, not NCR
2. Nuke Neither
3. Nuke Both
4. Nuke NCR
