Just finished the campaign, took me bout 17 hours with little divergence tbh, mostly focused on main quest.
Disappointing to hear that there seems to be so limited side quests then if most are allocated to the faction stuff =/
I did the railroad ending, so that immediately locks me out of anymore with 2 factions.
Some thoughts on the story as a whole:
This was all rather dull, no? I've not checked in here until now and have popped my head in the OT only a couple times but the world and characters just did not interest me this time around and I loved both NV and FO3.
The twist was silly: it made no sense. Why would the institute want only the baby, why no one else? Why just the baby>
If the source of DNA was they were looking for was so scarce why kill the mom so readily? "least we've got the backup"
Well you released him like 60 years later but clearly didn't care too much, leaving him wander the wasteland but you clearly have the capability to take and abduct people whenever.
Also, Kellogg not aging was also a shitty red herring, him being augmented or not.
The one thing I'll say for it is that it did leave me genuinely conflicted for quite some time as to who to side with, I thought that was quite well done.
Anyway I don't know if it was dependent, but the ending was frankly a damp squib. I got the railroad ending as I mentioned. It just stopped. Base explodes, end of. Don't really get a sense of change in the world at large now.
Also no confrontation with your son, I guess he just died in the explosion?
