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.
Fallout 4 siding with institute and railroad.
I like the bos all morality etc and everything else aside they re the only group that you feel their presence in the commonwealth they actually show up and do things randomly in locations while the railroad sits in its tomb the institute sits in its bunker and the minutemen sit behind their castle walls.
Has you commit genocide against three groups including the ones they were formed to help leave the commonwealth without a faction to keep the raiders super mutants or gunners in check the institute did even if it was for self serving reasons.
As simple as that.
Membership in the railroad may negatively affect relations with other main factions.
For fallout 4 on the playstation 4 a gamefaqs message board topic titled siding with the railroad vs.
The railroad shows synths as regular humans wanting a better life.
I usually side against the institute no matter what so i may be biased.
Telling the railroad about a compromise would go against everything they re fighting for.
While the institute shows you gabriel a synth whose memories were wiped who thinks he s human.
For people who sided with either the railroad or the institute.
You couldn t change the enclave in fallout 2 or 3.
It s a clear example of what a synth could be.
Siding with the minutemen.
Personally i like the bos things a bit better but that might be a carryover from the original fallout and fallout 3.
The more quests the sole survivor does for the railroad the more the institute and the brotherhood of steel will disapprove of their actions.
So in the end siding with the railroad.
Gabriel ends up leading a raider band in libertalia and ends up killing innocents for gain.
