That's just a longer chain of your choices, isn't it? Don't you find your statement contradicts itself? Because first your choices determine if you fuq someone or not and later your choices determine if you see her at the prologue.That is the other big issue, endings are determined by who you fuq with and not your choices.
And btw I am glad that this story is not like a Disney fairy-tail and the ending I achieved pretty much fits my expectation.
For those who are still upset: no one said that V won't find a way to transfer his identity to some construct chip and became the next Johny in someone's mind or just in some donor body (hello Altered Carbon) in Cyberpunk 2078. He did so much for 2 weeks, so he got enaugh time to achieve it for half a year.
