These days DayZ is a very hostile place. The biggest reason for that are many other players, who play it like COD.
So I am thinking about this for a couple of days, to make human interactions between players more realistic. I think nobody would hide in a Z-Apocalyse an shoot other surviors...
I think everybody should have an advantage from not killing others for no reason!
What if a "COD-Player" who just wants his kills, knows that he gets something or improve some kind of value, when he talks to someone, or help someone, without killing him??
My idea is, you could implement something like a "handshake".
Let me explain this idea:
You meet another player. You kill him: nothing happens.
But when you go to him and talk to him (and he does so too), both of you get +1 points in the gamestats (something like a "handshake-counter").
With it, you got something on every Player which can measure his friendliness.
In a second step, you could let choose every player on his own, if he wants to tell his amount of handshakes to the environment. Perhaps in a shown number when checking his pulse (as a way to adapt trust between to strangers), or a textoutput, when "handshaking" him like "I think he is a good one" or "I can't rate him".
Perhaps we need a way to show it players who are far away from your player, that they know the can interact with me without any harm (maybe an armlet or something).
With this improvement, i think most of players would have a reason for interact with others instead of killing them immediately and the game would be a little more interessting once again!
-getting a handshake and killing him afterwards should entail -1 handshakes.
-to avoid "farming handshakes", you can get just one handshake with the same player
