I like the idea. It has been pointed out that it would remove from immersion and realism; however, consider that the current game is not realistic in that people would not be killing everyone they see on sight if this, post-apocalyptic situation were real. In turn this makes it impossible to immerse yourself in the game when meeting a stranger in the world of DayZ. While it may not be a perfect fix, I think it would allow some immersion when meeting other players, by allowing options other than kill, die, or hide. I would like to see another feature introduced to your idea: dynamic characters. Obviously this would need to be tweaked as I didn't spend too much time developing the idea. What I mean by dynamic characters is the ability to go from good to bad and vice versa. An example would be someone who chose to play as a "good" character who ends up killing people would get the shakes and go a bit insane as you said, but eventually he would just become bad, his skin would change to show that and his insanity would fade over some time for game balance sake. Alternately a "bad" character could burn off murder counts or slowly go up from negative karma. This would take a very long time which could be supplemented with the killing of other "bad" players. The insanity sticking to a "good" player gone "bad" for a while, would make it so people wouldn't automatically choose to play a "good" player to be able to trick others as their insanity would take some time to wear off and they would be at a disadvantage until then. Also there would be a "perma-red" or "bad" forever status since raising your karma from killing a ton of people would take ages. People wouldn't just be able to sit afk in the forest burning off counts/raising karma over time. Like I said the, I like the idea. This FPS game needs changes if it wants to be a survivor simulator. What do you think about what I proposed?
