Wrong. The ncr already has the Mojave, but no thats not good enough, they want everything.
The gun runners were supplying before the ncr came along, they ncr just took them after they had thier industry going, vertibirds what few they have, were stolen fom the enclave, and PA was stolen from the brotherhood.
Parasites dont makeprogress, they die without a host, and the ncr is running out of things to leach off.
Lets see their veteran rangers wear old riot armour scavenged. Half of the army is in the mojave, all under supplied and under trained. They have been there 5 years. aside from taking loactions that were already established, all they have done is set up a few tents and placed a few flags.
Most towns are independent. Most of the places they own are military camps set up against the legion.
They don't have industry themselves (seeing they are a government and not a business), but California has industries. They don't have high-tech industry, though. It would be pretty silly if they built their own power-armor at this point, when before the war this was the height of war technology.
As you should have noted going through the story, the NCR has been trying to hold of the Legion's invasion, while dealing with raiders and such sorts inside the Mojave. This has been their focus and has stopped them from annexing the Strip. Not to mention that Mr. House doesn't want them to annex anything north of the Mojave outpost for his own plans. As long as Mr. House holds the strip they're limited in their actions.
Again ncr dosent build, the monorail, thats pre war, all they did was turn it on again. They couldnt get it fixed if anything broke due to no parts.
Mr house on the otherhand brought vegas back, and did so in under 7 years. That is a miracle, and shows how pathetic ncr is.
Not really, it shows the differences between the two. The NCR is less direct, starting diplomatically and then when that fails start do underhanded covert ops things. House he throws a large force of securitrons on the tribes occupying the Strip, boots out all but three, gives them the casinos and I'd wager throws some Mr. Handies in to construct the walls and repair the casinos. I wouldn't call it an all out miracle, he probably had that thing planned out years ago, I'd call it efficient and prepared.
As for not fixing the monorail, as I said they don't have high-tech industry. They do however lay down train-tracks which obviously means they have rebuilt trains and it's infrastructure in California.
How is house responsible ?? "Oh look this place isnt safe well its entirely his fault, he shouldnt have rebuilt, made an amazing economy, and focused on building". House strugglewith power outs, then rebuilt vegas, then domesticated 3 tribes (ncr just kills them) created an amazing economy, and now we are in the current situation. If you let house win, fiends are wiped out, securitrons go to Primm with high taxes (just like ncr only safer)
freeside is safer, and goodsprings. I would say he is spreading out. If you have good karma it says you enfluence his choices, unlike ncr which just thanks you and dose what it wants.
Under ncr roads are gaurded ? Lol I regularly get attacked, and what about nipton, where was the protection then ? Powder gangers ? Sloan ? The ncr cant protect anyone, take the mission to stop kimbals death, they cant even protect him if you do nothing.
Look at this, ncr kills house, house protects thier president from assassins. Hmm which side is better then ? The one who kills a man for not doing what he wants, or one who is just protecting his stuff while helping those who would wrong him ? I would think house is one of the onyl people on earth at the time that could be so kind.
First Primm is not safer without the NCR. And the protection is dubious, since they are there mostly to enforce House loyalty. There's no Securitron "help" if you made anyone else the sheriff.
Secondly NCR supposed incompetence is in part for gameplay reasons and the other part is actually explained ingame. It is important to separate things done for gameplay reasons from the story presented.
It would be very boring if you traveled along unhindered never encountering raiders or dangerous animals because of the NCR. This is why, if House held the Mojave, the game would have to make him incompetent. Heck without you, the Courier, House would still be trying to get his Platinum Chip. It be pretty boring if all sides had no use for you and those quests were already going to a competent [faction here] soldier/agent.
The NCR is focusing on a Legion invasion, while fighting off coordinated Fiend attacks, while Legion saboteurs throw them off. The game implies their troops are already occupied and California's political climate is holding back on sending proper reinforcements. This is given as an explanation of why they need someone like you so often.
Also House is not a kind man, he's a pragmatic man who knows the value of not being vilified. He can be nice, but really he's not the poor underdog fighting the good fight you make him out to be. Like all other factions he wants to see his own plans succeed. Also who is he helping that has wronged him.
As for being responsible, in part he is. The ending is quite clear that once the NCR and Legion are gone, the roads become a lot less safe and there are more refugees. He removes those patrols from the roads and can't/doesn't replace them. It's not some evil plot, but it's a point that can weigh in with a players (or his character's) decision.
