Major issue with DayZ at the moment, as far as gameplay design, is the complete lack of incentive to team up with other players. It's very easy to survive on your own if you're at least somewhat careful, so most people just shoot other players on sight because they see them as walking piņatas rather than potential allies. And of course this attitude spreads to other players when they get burned by someone they were trying to be nice to and communicate with, and so the the cycle continues. Playing with buddies using VOIP is great fun, but god help any loners that we stumble upon... It's not even so much about trying to be a bandit and murdering for fun, it's just that you can't trust strangers at all.
