Initially sided with the Railroad. Then Minutemen, which I hate, followed by bos which irks me as well. Finally.the Institute which was great in the I'M a sociopath sense. What can I say? Murder not for duty but for passion!
Then I said **** this shit! **** my husband, baby, codsworth, preston. I shall rule the wasteland!!!!
I dont think Ive gotten that far to be siding with anyone, but Ive been doing alot of the clear out an area/recover the tech missions for the BoS, the Miutemen want to take some castle back that Im too lazy to go & do, and Im currently working with the railroad to see where that gets me along with numerous secondary quests
I sided with the Institute. But I have a save file where I can go back and side with any of the others before it's too late. Mainly for the achievements I plan on getting... Someday.
At the start of the game, I figured I'd end up siding against the Institute, but by the time I had to start making choices, they were the only faction that didn't annoy the shit out of me. Preston ruined the Minutemen for me (so I ruined the Minutemen to return the favor), the Railroad were just a bunch of naive bleeding-heart idealists, and Bethesda seems to have made the BoS into much bigger dicks than in the last games (or maybe I just had too many big guns to let some douchebag in a trashcan talk down to me)
After getting all the DLCs and getting as far into each arc without making a "final" decision I'm stuck. I want to 100% nuka world, but dont want the raider camps to kill the work I've done in the commonwealth. The minute-men are the choice to go with since they haven't screwed anyone over, but also the most bland. The BOS are a bunch of religious zealots along the same lines with the children of atom. The railroad mean well, but use cutthroat methods to achieve their ends. Ugh. Sorry for the ramblings.
