Cyberpunk 2020 has a very black and white line for cyberpsycosis; above a certain level of humanity everything is fine, then one point over and bam, crazy street. NPC time.

What I'm looking for is something to help with gradual loss of humanity; I've found a few things online, such as neurosis for certain implants, but what I'm looking at is something to indicate what is going on.

I rather like the humanity system for Vampire and have been trying to toy with a way to use that as well.

What I'm looking for:

  • Rules to manage gradual dengeration of a characters humanity score
  • Rules to manage how affected a character is by seeing horrible horrible things

Cyber-psychosis doesn't just happen, its the result of losing all empathy for other human beings.

The line at which a PC becomes a rampaging cyber-psycho NPC controlled by a GM does occur when a PC's EM stat reaches zero, but this doesn't just happen, a player made a choice to get yet another piece of hardware and overwhelmed themselves in the process. Empathy is a bit of a unique stat for CP2020 in that it doesn't simply represent a skill or ability, but also your state of mind.

"This Stat represents how well you relate to other living things--a measure of charisma and sympathetic emotions. In a world of alienated, future-shocked survivors, the ability to be "human can no longer betaken for granted. Empathy (EM) is critical when leading, convincing, seducing or perceiving emotional undercurrents. Empathy is also a measure of how close he/she is to the line between feeling human being and cold blooded cyber-monster (see pg. 73 for details). - Cyberpunk Core Book p. 26

Because you lose a point of EM for each 10 humanity points lost to cyberware installation the process will be cumulative over time as they cyber up.

There are no published Sanity rules for CP2020

I don't believe that there was every a sanity rule option introduced in any of the chrome books. It is out of tone with the game that they published and the genre as a whole. That isn't to say that you shouldn't do it, simply that the publishers didn't feel it fit.

Fan's have created their own sanity system however based on Chaosium's Call of Cthulu system.

Over at Wlydeside (a fan community), someone has ported/created a sanity stat for Cyberpunk 2020. Essentially you add EM, COOL, and LUCK together and times that by 3 and you have the sanity percentage a character has. Call of Cthulu uses percentile dice for everything so you could have players make sanity checks by rolling 2d10s. and having ill effects if they roll over and have things in the campaign consistently bring their sanity down in the way humanity points lower EM.

    \$\begingroup\$ I think the take-away here is to put a greater focus upon the empathy loss and role-play its effects. If one is looking to Vampire's Humanity system as a model, you could involve EM or humanity points in more rolls, or adjust how kindly NPCs react to a character based upon it. \$\endgroup\$ – Jessa Apr 6 '15 at 18:50

If you want a (very) quick similar rules, use Humanity score as Sanity in Call of Cthulhu, and roll 1D100 Humanity this to check for stressful situations, and (very) quick sanity loses could be:

1d6/2: Low stress situation.

1D6: Medium stress situation.

1D10: High stress situation.

Use +1 to +3 modifiers to create intermediate values on those categories.

The lossing of 1 EMP point for every 10 humanity goes well with the gradual degradation of humanity.

If you want to add some "sanity armor" then get COOL and use the same table as BOD for BTM, so very cool characters don't get impressed easily, a 10 COOL guy would get a -4 to sanity loss, so only some medium or high stress would affect them.

You can get the exact sanity loss from Call of Cthulhu, but since it uses other dice (D8, D6) I quickly made this system for dice used on CP2020
