Mayer Foner, of M. Foner’s Games Only Emporium (aka That Game Place) has created a game called A Game About the Pennsylvania Underground Railroad 1820 to 1870. It’s based on a previous work called The Central PA Underground Railroad Game, about which I can find no information.

Each player gets 35 turns to escape without being caught and returned as a slave.

This wouldn’t be the first game about the Underground Railroad; Chattam Hill released one in 1993.
