Trying to write this in minimal spoiler language.

I'm at the point in the game where I have a piece of info regarding the institute. I have 3 parties who want the data, but can only give it to 1. Am I guaranteed to have to piss off 2 of the 3 parties no matter what I do? I am very attached to 2 of the 3 parties and their ideals (I think in theory they could work with one another - there goals are not mutually exclusive).

Any major spoiler-free advice would be appreciated.

not that I know of

You can give the data to all 3 eventually. They wont get mad if you give it to the others.

Thanks, that puts me at ease.

Aww man, I liked your post cause it asked for spoiler free answers... I think the response you got that you can give the data to all three eventually isn't too spoilerific, but kinda sad I read on to far. Good post though,,, I was thinking of the same question.

of the main quest factions? absolutely not. Although two of the factions reasons for hating each other is very very weak.

The only way to hit the endgame with three "happy" (that is to say, non-hostile) factions is with the Minuteman ending. You pretty much have to string along all four factions until Battle of Bunker Hill and at the end of that you pretty much tell Father to stuff it where the sun don't shine and get banished from the Institute. The Minuteman quests are all safe, but care must be taken with the Railroad and Brotherhood quests since they hate each other. Go too far down one of their quest lines and the other faction will become hostile.
