Hey guys! I have one interesting idea about Day Z: the game could copy libemocha.com's points system, in this site you help somebody correcting his/her language exercises and you earn points, then you use it to buy lessons on language courses there. Day Z could copy this to (re)create "humanity" points, you help somebody, giving food, bandages or walking with other player for some time then you earn points, other players would see your points when they come closer to you, when you shoot somebody close to you, you loose points. These points would start when you press a "fire friend" button to another player. You can use these points to buy some items in specific places, or it would has a ranking of these points and depending on players' points, some areas are open (unlocked) to them, like camp bases, or markets. The idea represents a "reputation" for a player that helps others (a kind of reward system) and when a player is trustable he would be welcome in safe places.
