Est. 1879 · an informal map, drawn in dirt with a stick

Books that ship with terrain.

Every novel here comes with a world you can walk into and a game that teaches the one mechanism the book is actually about. The fiction carries the argument. The game makes you feel the arithmetic.

Each teaches the one mechanism its book is actually about. Under five minutes to your first failure, and the failure is the lesson.

Why a map you can walk into

A mud map is a rough guide scratched in the dirt for someone who does not know the country. It never claimed to be survey-grade. That is the honest posture for fiction that teaches: the model is simplified, the simplifications are stated out loud, and what you are left holding is a shape you can reason with rather than a set of facts to take on trust.

Every game on this site ends the same way — with a card telling you what was faithful and what was cut. The map is not the ground, and we would rather say so than have you find out.
