I want a survival game. In your honest, whole-hearted opinions excluding bias. Does DayZ deliver the tense, jittery feeling of a survival simulator? I'd like to make sure what I invest is in a good purchase, I' am well aware the game is in Alpha and has a slow development process. Also, if you could list pros and cons of the game from your own experiences, that would be absolutely helpful. I'm actually looking forward to this game, but I'm on a budget, so I need to make sure the $40 I spend will be a worthwhile.
