“[The Midderlands] as a small area campaign supplement is the best I’ve ever seen, displacing Dave Arneson’s Blackmoor First Fantasy Campaign area, which up until now -- and that’s decades -- has been my favorite one.” - Matt Finch (Creator of Swords & Wizardry).What is going to be in the new 'The Midderlands Expanded' book?
A Gonzo Post-Apocalyptic Campaign Setting and Sourcebook based on the articles of Crawling Under a Broken Moon

Our design goals were simple: make a game that's mechanically compatible with OSR retroclones (and their mountains of content) while leveraging the compact but non-binary PbtA system.So yeah, intriguing.

 - Player-generated character traits instead of predefined playbooks or attributes
 - High character lethality
 - Strong GM authority
