First of all it is the best option for the courier. For delivering the platinum chip, you are rewarded 1,000 caps, and a suite. With the NCR, you get some caps, which isnt bad, but with House you get a penthouse suit. In the endgame, your are basically rewarded with ownership of the Lucky 38, which after it is reopened will take almost all of the other casinos customer base away, given it has not been opened for 200 years and is viewed with reverence and awe on the strip. It is most likely it will pull in over 30,000 caps a week. People will come from all across the Mojave and NCR to gamble and drink. Remember House controls all of the industry on the strip, so he will take a lions share of the profits created (which are huge already). Imagine the benefit you as the courier could garner from this? After the main story is finished you are effectively Houses oddjob handyman, but an oddjob handyman who lives in a penthouse suit and is inordinately rich. After the end of the game, it is not mentioned, but it is obvious House will enrich the courier beyond imagining, for helping him with his grand scheme. Also the courier can rest assured humanities future is in competent hands. Also he will give you immortality, with his special life preserving machines. "With all that money pouring in? Give me 20 years, and I'll reignite the high technology development sectors. 50 years, and I'll have people in orbit. 100 years, and my colony ships will be heading for the stars, to search for planets unpolluted by the wrath and folly of a bygone generation." WOW. That is incredible, compared humanity being guided under a corrupt, bloated and pretty useless government, the NCR. (By endgame House has them on his payroll anyway). Another alternative is a brutalising dictatorship, where crucifixions and burnings happen on a daily basis in the name of homeland security, modern medicine is banned and inaccessible, and you will be executed for minor offences. Dear me, House sounds better. "They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." - Benjamin Franklin House is not a person who takes essential liberty, Caesar is. He banned homosexual behaviour. "I have no interest in abusing others, just as I have no interest in legislating or otherwise dictating what people do in their private time. Nor have I any interest in being worshipped as some kind of machine god messiah. I am impervious to such corrupting ambitions." Many claim the legion is at an advantage given there is no corruption. Rubbish, it may have no corruption, but House is not corrupt at all, and he refrains from all the extreme violence and doesn't have a crucifixion fetish. He takes a Laissez Faire approach to the wasteland, and I am sure many in the wasteland would rather be left alone to sit in shit all day than be crucified and/or raped and burned, with strong men being conscripted and women being breeding tools. NCR is too lazy and rotten to do anything anyway. They are too busy with imperialism to care. House is a dictator, but a good one. (They exist). He is not gonna indulge in some kind of Stalin style purge on a whim, or regulate peoples lives. He is a good leader. He is immune to bribes from people like brahmin barons, hell, House could probably bribe the brahmin barons if he wanted to. He has no sex life, given he is basically a sentient potato crisp at this point, so nobody can send in some hot babe to convince him to do other peoples will. After he is done with the dam, he will annihilate the kings and gangs in New Vegas. He will probably renovate the area, since why would he want some smelly slum next to the beautiful jewel of the wasteland. You, the courier, have a modicum of influence on Houses decisions, so perhaps you could convince him to fund the Followers of the Apocalypse? Some good points from a clever dude on Reddit: "1 - House has access to a treasure trove of technical resources from the REPCONN headquarters and launch site. With all the money from the casinos and manpower clogging up Freeside, House can effectively build up a workforce of technical specialists. 2 - The U.S and China were fighting on the Moon in the Sea of Tranquillity. Considering this, they more than likely had lunar facilities to deploy troops/fighters to attack one another. If there are any leftover facilities, House wouldn't even need to start from scratch on Earth. All he'd have to do is send enough people on rockets to these abandoned lunar facilities and get them working on making them operational. If he's lucky, he might scavenge information that could lead to him producing even more effective colony ships, but at the very least he has access to the Moon. Once there is a working base/outpost on the Moon, House has a backup plan in the event that Vegas is compromised again by a desperate NCR/Legion onslaught. With at least 10,000 people and all the technology he can scrounge up from the Mojave, House can produce a lunar colony that is viable and self-sufficient in most concerns. He'd still need salvage, but that is assuming he loses Vegas in the process of taking hold of the Moon.Earth was drained before the war, and that's the real problem nobody wants to acknowledge. The NCR can extend more and more until it collapses on itself, but even if it sticks to the West Coast they'll eventually run out of arable land and salvageable goods. House isn't looking at keeping his bets on a rotten planet, he plans to get the hell out and avoid the inevitable Malthusian collapse of post-war societies.he NCR is only interested in repeating the mistakes of the U.S without the resources to keep recovering from the consequences, while the Legion is actually marginally better in that they'd use less resources as a society. Even then, they too would run out of scrap/resources and fall apart just like the N.C.R.". House is taking successful pre war society, removing the fatal flaws, and leading humanity to a better future in the stars.
