All of the #1 with a Bullet Point products are short and to the point, they come with a big idea and then the mechanics to implement it.
15 Fantasy Fees and Taxes: exactly what it says, fifteen mostly obscure (to modern people) taxes and charges that existed in the past as various ways for the state to acquire money and impose economic stability. Several are fun and almost all will be annoying. If you like finding ways to bedevil your characters enjoy this product (which was released on tax day for bonus amusement).
