I disagree. This is cyberpunk, distopian world, no happy endings, rings a bell? And you want your oryginal V? Please....
But jokes aside
, i still disagree but i will admit that there are many things unclear or even can be called plotholes. First of all there is no such a thing as "exctract" memories and personality. What you get is a copy. Brain is biological, with myriad of states and processes running. That is what defines "you". Relic damages it, rewrites it biologically, hence the need of nanites.
When V plugs into mikoshi, the soulkiller is used by alt. And soulkiller is a virus, a program, digital one, so it goes into every implant you have to gather data about V brain state, to relic propably too. Then it wipes the personality to leave the brain in "empty" state( How can it wipe it I have no idea,I would call it plot hole, or maybe someone can explain it? It is some kind of electrical impulse? I fail to see how can it be done or just makes the brain cease all neural activity by shutting down implants? ). At that moment, V is just clunk of unorganised bits. With data gathered alt recreates V personality in digital form, corrects errors, ( Can we be sure that all of V was copied succesfully? When you read relic documentation you can see that volition fluctuates at 80-90% conformity and emotional output at 75% conformity levels so it's certainly not perfect). Then engram is copied again into V's body( But into what? Relic? Alt said that she stopped him from working to stop overriding V, if she would have restarted him with V engram it would again go to work to fix the damage done.... and there would be no 6 months BS, into brain? Then relic and nanites are unnessesary if you can override everything directly.) So im assuming that relic became intergral part of the brain and assumed some functions of it. That's why Engram V can still control body as engram. And nanites don't work. So in my perspective changed a lot.( Even alt and johnny knows it, remember the conversation in first meeting? "It changes everything". And to clarify - Brain as centre of oryginal V vs relic as centre of Engram V).
There are many things that don't make sense and it is supposed to be a science fiction. Not fantasy. I would agree in fantasy setting to some magic mambo jambo that can pull inbrain, fix it , then put back but in SF it should make sense...
In case of DLC, what do you think , will we get info in 2021? Or not?
