By far the number one killer of realism is the amount of PvP in the game. PvP is not bad at all in the right context, but the game is sorely lacking the ability to generate fear of death. In a real life Day Z event you would have people banding together to survive instead of turning into serial murderers. Rocket threw out the possibility of having your gun lowered until you press space. This is an interesting idea, but one which I believe won't do much to curb the mass killing currently going on. Right now there are incentives to kill other players: prevent yourself from being killed, acquire additional gear and the thrill of saying, "I won!". These incentives to kill far outweigh the incentives to remain peaceful. Ideas that I've thought of to address this are: Towns and Cities should be far more dangerous. Firing a gun in one should nearly guarantee your own death. Include varying types of body armor that can be picked up in-game to make dying to bullets much less likely. Implement a respawn timer based on your currently humanity. The lower your humanity the longer you have to wait to respawn. Cause weapons and gear to become damaged and unusable if shot. (Lighting a player up with a dozen bullets would likely render almost all of the gear on his body inoperable.) Increase the amount of time needed and difficulty needed to gain humanity (max 250 humanity/day, only gained by helping players who you haven't helped in a few days, etc.), but also provide additional body armor to heroes. The rationale behind these suggestions is to create a greater sense of fear of death as well as reduce the incentive for all players to be serial murderers. Because, let's face it, there's just no realism at all in everyone trying to kill everyone else. The reason this doesn't happen in real life is because no one wants to die. With the current state of DayZ many players don't care about dying, which makes everyone shoot on sight. I welcome any thoughtful discourse on these suggestions!
