My biggest complaint right now is that there is really no 'Real' need for people to work together. The game needs coop functionality, besides the basic survival/shooter/socializing aspects. Even Rust and 7 days to die (alphas) are far ahead of this in terms of things to build, craft, etc.
My first impressions were this: The Running Simulator, which is what this game pretty much comes down too, and that every one person I tried to meet turned out to be a psychopath, probably so bored all they do is shoot/kill you, ask questions later. And later to find out that if your server has a Voip, get on it, meet the people and enjoy the game more (which I have now.) If your on TS, etc with some people its more enjoyable.
