Really digging this so far, its right up my alley so that was pretty much a given. I started out on Medium, but I wanted more of a challenge so I bumped it up to hard. I got to year 10 with about 30 adults and 10'ish kids, thought I was doing pretty well, just built a mine and quarry, and then everything tanked. Couldn't keep up with food production or firewood. I gave up once I was down to about 15 adults, about to start a new game. I think what killed me was lack of school for too long, I'm not too sure. Education effects productivity, and you start out with some educated adults, so your beginning productivity is decent. I think most or all of my original educated adults died off to old age, which lowered my productivity overall and I just wasn't able to keep up and sustain.
