I've got this thinking it's going to be awesome, this was a couple of months ago and I wasn't impressed to say the least. You start on the beach with nothing, you hit trees which drop wood... you pick up stones. Doing this gets you a level up so you can research how to make things like axes, clothes, huts... find materials to make them, click "build" to make the item and either use it or place it. Might have changed now, could do with going back on it really :)
