You couldn t change the enclave in fallout 2 or 3.
Fallout 4 siding with institute and railroad.
If the sole survivor sides with the brotherhood of steel or the institute they are eventually sent to exterminate the railroad as the organization s motives oppose both of the former parties goals in the region.
The railroad shows synths as regular humans wanting a better life.
While the institute shows you gabriel a synth whose memories were wiped who thinks he s human.
Membership in the railroad may negatively affect relations with other main factions.
Siding with institute turns ss into kellog 2 0.
Gabriel ends up leading a raider band in libertalia and ends up killing innocents for gain.
Siding against the railroad means you d be picking up more reinforced railroad coats gauss rifles and raillway rifles.
As simple as that.
The more quests the sole survivor does for the railroad the more the institute and the brotherhood of steel will disapprove of their actions.
Telling the railroad about a compromise would go against everything they re fighting for.
Siding with the minutemen.
I usually side against the institute no matter what so i may be biased.
For people who sided with either the railroad or the institute.
Personally i like the bos things a bit better but that might be a carryover from the original fallout and fallout 3.
They re looking to free synths not make a deal with the institute.
For fallout 4 on the playstation 4 a gamefaqs message board topic titled siding with the railroad vs.
So in the end siding with the railroad.
