Am guessing I don't need to mark anything as spoiler because the thread title does it already and it's to be expected.
That's it. Rest is cosmetic choices, but basically your choices doesn't matter- you die anyway.
Depends on how you define "dying" - if I get it right, a "copy" of you exists in one ending, safely tucked away in Arasaka's lap. Or labs. Databases. Vaults. You get the idea.
A potential follow-up connection to the next game, assuming we get to step in the shoes of "V" again as a continuation of this game's protagonist.
It's very odd how the story is written as if Johnny's engram is Johnny himself back from the dead, instead of acknowledging that it's just a copy that's acting as random neuro-malware and killing an innocent person.
It's not like there are or were no clues. In my pro-Arasaka ending I went down with the "princess" and after the first engram contact, requested to see Jackie Welles post-mortem engram. Granted, they got it from a deceased person but at one point V can either bid farewell or coldly say "I've seen enough, it's not him".
It's not the same person but a copy if I got it right and there's no one to one transfer possible. It would be like copy-pasting a file or folder and deleting the first after that - the copied one never is the same folder.
Long story short, I think this is the big "reveal" or "twist": It seems like you said on first glance or for a while - until you realize it's not. At least, I did or think I did in my game.
Saved my V - well, did I really? Just a copy, that is.
