Cold Iron is a complete tabletop role-playing game, including rules, a setting, a handful of classes, and two short sample adventures, all contained in a single zine. The rules are simple enough to grasp even if you aren’t familiar with other TTRPGs. They are designed to encourage a variety of problem-solving approaches from diplomacy, to physical acumen, to outright violence under a unified rule set that requires very few “special case” rules, while still allowing specific player actions to have granular effect.
