From publisher blurb:
Tiny Frontiers is a minimalist roleplaying game, designed for fast character creation, swift action resolution, and maximum flexibility.
Using the rules within this rulebook, you and your friends will be able to explore the unknown reaches of faraway galaxies, topple evil interstellar empires, swash and buckle with vicious space pirates, and battle in colossal mechs above crumbling planets.
The book also contains 16 "micro-settings", small, evocative settings designed by RPG industry veterans, best-selling fiction authors, and many more top-level contributors!
So go forth, and explore!
