Since DayZ is (or should be) a zombie apocalipse simulator, not a military simulator, here are my suggestions: Killing other players PVP is good for the game, but not when it becomes the only point of the game. When you kill another player in a videogame it has no consecuences, and is fun, so becoming a bandit for no reason is the easy option, and like is happening with DayZ mod, the player interaction other than shoot first, then ask becomes almost nullified. In a real world, killing other person for no reason (or even with a reason) is not as easy, and it has a great psychological impact. So I think humanity should be used to simulate that situations, and to add a cost for being a bandit: - A player killing another player for no reason (for example, he isn't very hungry or thirsty with no food on inventory) should get a great humanity decrease. - Negative humanity should have negative effects on the player. A psychologial effect. First he can start having shakes (adrenaline and guiltyness). Then he can start speaking alone (revealing his position). And with a very negative humanity, he can start becoming mad (similar to random blackouts when low blood, he can start losing character control. Let's say, the character do weird things like starting to run for no reason, or start shooting to air due to madness). Other kind of things could be lack of famine, degrading his health in th same way of eating always the same food. - Exceptions to these humanity decrease could be things like self-defence, or shooting a "flagged" player. FLAGS A flagged player is a player who you can shoot with no (or very low) humanity consecuences: - A player that robbed you - A player who shooted you - A "war declaration". That war declaration should be for groups (so should be a mechanic to make groups). This kind of thing could be used for players willing to play pvp with another group of players, for example defending their camps, without ruining the playstyle of other players, or loners being shooted for no reason at all. OTHER SUGGESTIONS - Zombies should be a real threat in the game, not a secondary threat compared with players. - Military grade weapons like sniper rifles or launchers should be non existant, or extremelly rare (like 1 or 2 in the entire map), and their ammo too. Civilian weapons should be more important for a game like this. A game full of snipers is just gamebreaking like we already experienced on DayZ mod, and the game loses their whole point. I know some pleople likes that kind of playstyle, but there are already tons of games for doing that, and in this game it doesn't make sense. - Sneaking robbing should be more exciting and rewarding that shoot and rob. Mechanics for that would be cool. - Overall, the game should be focused on survivalism, adding tons of features for that, and leaving pvp as a feature more, not the most important feature. SURVIVALISM - Fishing - Lockpicking (doors, boxes) - Cure researching (end game feature) - Clothing sewing (repair) - Hunting traps
