I would find it interesting if you perhaps drop at least one random item when you die, so that you still would have to stay cautious when trading with strangers. I want the possibility of being robbed. The idea of having a friend staying hidden somewhere with a sniper rifle, covering me in case things go sour, is pretty damned awesome.
Or pointing a shotgun to the side of his head lawl. Drop trading just seems bad in a way though, like a few possibilites for things to go sour...But whatever the game decides on i'll accept really.
Like I said, im sure there will be certain options for server owners, in the FAQ it is mentioned there there will be a form of "hardcore" mode. Which im sure would have some form of major losses when you die, basically starting from scratch as a new survivor.
I think there should be some form of loss when you die, like food was mentioned already being implimented, and also a form of risk when trading.
