Hi

Im asking about what stage am i in the game right now. I have the quest "the molecular level" where i need to go talk with either minutemen, railroad or brotherhood.

If i now choose lets say brotherhood of steal does that prevent me from doing other quests for other factions?

How far am i on the game now? 50%? 70%?

Is going into the institute via teleporter the last mainline quest to do?

At what point am i doing the "no way back" quests for the other factions?(i want to avoid that to do as many quests as possible.

Thanks for your answers.

That isn't the point of no return...

The point of no return occurs in the factions' questlines and you'll get a confirmation if you're abou to trigger it IIRC

It is the second last faction common main-storyline quest

There is a way to make peace between almost everyone... but its rather interesting timing on it. If your curious check out the walkthough/tutorial below.

How far am i on % of game completed(main quest line)`?

Im 51lvl by the way, so im thinking im nearly in the last parts (70-80% completed) am i right?

Yeah, I'd say so.

I was level 63 when I finished the main story (BoS path).
