I'm still finding my way in MineZ, in an experience that echoes both people discovering Minecraft for the first time, and people discovering Day Z for the first time. I've yet to kill for anything other reason than preservation, though, and I'm not counting it out when it comes to revenge for a previous killing, or stopping an attack in front of me. I've not planted wheat or uncovered what the green dyes purpose is. But, again, like DayZ and early Minecraft, part of the fun is the discovery. It's possible I'll have seen enough when I know how it all works. Or its possible it will evolve and draw me in further still.
