Tombstone - Grit & Determination is an adventure game about exploring the badlands around a few settlements out west, a land filled with adventure, odd folk, adventure, and danger in them thar hills. Character creation is quick and random needingly only a deck of cards. Advancement is based on play rather than classes or laid out archetypes. It was originally based on Cairn by Yochai Gal and Into the Odd by Chris McDowall, and still makes references to the work by those two individuals. The game is written by Tom Sweo.
