MEST - Adventures In Matter, Energy, Space and Time is a set of free wargames rules for cinematic skirmish games. The authors write:
Matter. Energy. Space. Time. The MEST Narrative miniatures rules system is designed to be a flexible light-weight set of features that can work with numerous genres such as Swords & Sandals, Medieval, Swashbuckler, Wild West, Horror, Victorian Adventure, Pulp Heroes, Modern Battles, Future War, Sci-Fi, or Superheroes.
With these rules two or more players can simulate the last exciting minutes of derring-do, harrowing deeds, and heart-stopping acts of courage of any small-scale engagement pulled from any number of genres; from penny novels, serials, and otherwise. Will the dastardly villains win? Will the heroes prevail? Who lives? Who dies? The answers to these questions and more await your decision!
