Its directly from tabletop, you have intelligence,strength etc and humanity as attributes in 2 (I think) to 10 scale. So you can have a cold inhuman killer or somebody that feels the pain of somebody burning its lips while sipping tea (just pure empathic).Mmm yea...bloodlines did it very well. But why in character creation? Wouldn't it be better/more natural if your decisions led you to the more aggressive dialogue?
Strictly speaking should be a one way ticket, easy to loose humanity almost impossible to recover... but balancing for funny gameplay (its a game at the end) would probably be a good idea.I will say maybe a nonsense, but I think that would be a "base" choice of your V.
You don't get empathy/humanity based on your actions/responses during the game (could be developped as things progress, but you have to choose it at the start), you either have it or not (well I think).
I see one issue with a questline that makes V a cyberpsycho (or at the edge) that is that you already have somehow divided opinions about the Relic and Johnny; not sure how something that "forces" the player to do some actions or so will be received.I agree, I even had a whole long concept on representing empathy through a "human perception" stat if they didn't to limit dialogue with humanity cost ... but this thread was about missed stories not mechanics. I'd take psychosis impacting a borged out V however I can get it.
Maybe an approach would be the Max-Tac with Melissa but not in "SWAT" mode. I was thinking about old A.D. Police OVA where you have the "grunts" and the detective side. Taking into account that many people wanted more Max-Tac,NCPD work and in general River questlines are appreaciated could be a way to put cyberpsychosis, and since its more or less stated that Max-Tac themselves are almost full psychos then maybe you can put V in some psycho situation.
