Great adaptation of the Apocalypse World framework to promote a political, seasonal and adaptive game far greater in scope than its predeccessor. Take command of a family and build a new world in the shadow of civilization's death spasm, and watch that world and family change in ways within and beyond your control.

This book is beautiful, with UFO's clear design interspersed with amazing impressionist artwork that carries the seeds of this world's incredible potential. The design is rich, with a lot of moves to keep track of, but their context is delineated cleanly. For those who loved the generational play of Pendragon, this takes the idea to wild new places, with characters receiving their own jolting arcs in the face of turning ages. 

The Titanomachy demo is also probably one of the best adventure kits/tutorials that I've ever seen in indie gaming to boot, so check this out.
