Which quests will I miss by joining a certain faction?

[K4ever]

So I almost finished blind betrayal by not killing danse and by not talking to maxon. Im about to start the battle at bunker hill, and the railroad is asking me to free more synths from the institute. I still havent reach a point of no return, but I know its coming. I just want to do all possible quests from every faction before i get locked from doing some by allying myself to an specific group. BOS has been discarded already from my thoughts and Im still undecided whether the railroad or the institute should be my ally. I think that with more quests I will be able to see a little more of the story behind these 2 factions, and that will let me have a better idea which side to choose.

There is one way to have no point of no reaturn for everyone but the Insitute. check out this youtube https://www.youtube.com/watch?v=OUFEeYdQnVc and you'll see you can have the Railroad, Minutemen, BoS all survive. Its not easy and you have to do certain missions in an certain order but it's doable.

To get the good ending where all 3 factions (BOS, RR & MM) survive and all 3 factions love you, all you need to do is NOT DO the faction missions that would pit you against another (e.g. Tactical Thinking for BOS, Mass Fusion for RR as part of the undercover questline), and then side with MM for Nuclear option (which is the only one option at this point ANYWAY), and THAT'S IT.

So to answer your question OP, you can join all 3 factions and the Institute and do all the quests and sidequests you want in any order except the quests that would force you to fight another faction (except fight agaisnt the Insittute obviously). If you don't actually care about the BOS, you can actually proceed to do a bunch of quests for the Institute and RR without worrying about anything until the point where their paths diverge.

You can refer to this chart to see which quest you will miss. The route that will allow you to complete the most mission would be to side with RR which would allow you to do all of RR's mission plus 90% of the Institute's missions and most of BOS' mission up until Tactical Thinking (and you could have done most if not all of their sidequests by this point).
