So I am doing a short run of Apocalypse World for my weekly Games on Demand Skype game. The last session was our first, and everyone seemed to enjoy it, but there was one comment that they did not feel the "Pockets of humanity" bit was really being represented in the fiction. And, well, I suppose it was not not, and I am not entirely sure how to do so. Basic concept of our Maelstrom, an AI ran everything on the world, nanites regulated the atmosphere and captured a persons "Soul" when they died to bring them to "Heaven" a collection of satellites that orbit the earth, and maintain the "Matrix." Well, it all went wrong, and the climate control system scourers the wasteland as it is controlled by the mad AI and collected souls. The world survives in small pockets of naturally environmentally stable areas, and others that have archaic systems able to ward off the nanite bots that control the weather.
So with that as the basis of the setting, what are some good ways of showing the "Pockets of humanity" theme?
