Revolution Comes to the Kingdom (RCTK) is a tabletop roleplaying game about a small country in civil war after WWII. You travel to each of its eight valleys, lead the people to a spiritual awakening, confront the monsters that lurk in the dreamlike catacombs beneath each valley, and free the Kingdom!

It’s a game of difficult journeys, raids, prison breaks, foreign mercenaries, code books, sniffer dogs barking along the banks of a river. It's also a game of spiritual awakening, exploration of ancient places, visions of awe and terror, and struggle against the Eight Evil Thoughts.

"Playing the Game" gives you everything you need to start playing right away. The other parts - "A Welcome in the Hillsides" (setting) and "GM's Toolkit" - are available to Patreon supporters. RCTK is in active development, and this is a beta release.
