It looks like the survival bits are probably really solid, from the look of things. The resource gathering bits are less clear to me in terms of how they work and what they're good for. I'm getting really spoiled on 7 Days To Die at the moment, heh. I have 48 hours on that game since I got it on the 6th of the month! That's just an incredible volume of play for me compared to what I normally would do.
