[FULL GAME SPOILERS] Who were the Monsters?

[humanoid]

I'm not sure what did you think you are stating by this but if I had to make a far-fetched assumptions (and I HAVE to since most of your replies and statements are empty, very vague that leave you the room to wiggle an ABSOLUTELY pointless debate or poke opponent with "no, you got it wrong, this is what I meant!"; if you meant to say something then ffs say it as it is) the effect is quite vice versa: "appendix" is the reason i bothered to reply to you and elaborate my reply.

What exactly about that is unclear? I don't feel the need to express my thoughts over dozens of paragraphs every time so even the most simple minded person can understand it.
If my posts are "empty and very vague" for you then don't reply to them, its as simple as that.
On the other hand if you are not sure about the thoughts behind my text and want to discuss it with me, just ask for a more in-depth explanation instead of interpreting it your way and implying that I have no clue what the game was about.
Which btw was the whole reason I felt the need to reply to you, not because I "want to dwell in demagogy or debate for the sake of a debate".

But if you're asking for it, here's what I meant with the appendix:
In Pathos-II there were originally 55-60 people after the asteroid hit the earth, however during the game we encounter/read about only a fraction of them.
Therefore it might be impossible to figure out the original identity/backstory behind every monster in the game (which is the point of this thread) unless we are given more of the official story or "make insane hypothesis or write fanfics".

Sharpshooter much? ...
Aker's is a "brain scan of itself" or so to say, you could easily figure it out if you apply some thinking to the thought.

I'm not quite sure what about that is "sharpshooting" (or in your words cherry picking) but perhaps our definition of a "brain scan" is different.
By my definition its a copy of a consciousness that doesn't linger in its original body anymore (in other words, the copy is stored outside the original body).
In case of Akers I would speak of an alteration of the original consciousness instead of a brain scan of himself, like I mentioned in my previous post (the part which you apparently conveniently skipped despite just complaining that I should express myself more clearly).
Feel free to tell me I'm nit-picky about this but those are two very different things in my opinion.

That's why in a productive discussion we usually realize that we need to stop making insane hypothesis or write fanfics in the threads and actually try to work your way from known facts using all official lore and data.

And why are you telling me this? You were the one who started with the assumption that "whatever monster you see in the game - has a base brain scan of someone", despite having no evidence for it.

But since any more discussion about this little quarrel would be truly pointless I'll just end my part here by saying that this discussion is definition dependant - and we seem to have quite a few different definitions for things.
