Simple: Open Adventure was born from a need for a simple, easy-to-learn game that could be taught in 10-20 minutes to someone who has never before played adventure or role-playing games.

Made for All Ages: Modern day RPGs can span upwards of 600 pages in rules. We wanted to bring back the "For Ages 10 and Up" moniker by keeping the rules lite (no more than 161 pages of rules per book), and simple English for all to enjoy.

One Mechanic: Instead of using a hundred different mechanics to represent a hundred different situations, we use one common mechanic to handle skill tests, saves, combat and so much more! For players, once they learn the simple "1d6 - 1d6" mechanic, they're ready to go!

Common Materials: No more will you have to buy funny-looking dice at a specialty shop. A couple of six-sided dice scavenged from a board game sitting in your closet will do just fine. No dice? No problem! You can use playing cards or even a rock-paper-scissors style alternative for the entirety of Open Adventure.

Limitless: Open Adventure doesn't lock players into a finite set of character types (known as classes). Instead, archetypes offer a broad set of characters that can be mixed and matched with in-game roles to form thousands of combinations! Races & species are limitless, since anyone can play as anything (including a creation of their own design). The dice system used throughout Open Adventure can be scaled infinitely to fit anything from the mightiest of planet-smashers to the meekest of mice.

Free & Libre: Who doesn't like free stuff? Not only is Open Adventure free to print and play, it's open source–meaning you're free to make your own changes to suit your play style. It's truly a game by the community, for the community.

Two Games in One: Do you prefer chocolate or vanilla? Why not both? In Open Adventure, two game genres are supported out-of-box: medieval fantasy such as you'd find in the tales of Lord of the Rings or Beowulf and science-fiction similar to Star Wars or Star Trek. Whichever one is your preference, you're sure to have fun casting spells or sailing the stars. If you're really feeling adventurous, why not mix and match the two? But that's not all! With a little modification, Open Adventure can be made to play just about any other genre of adventure game (post-apocalyptic, horror, western, etc.)!

Endless Play: There is no end to the fun! You can play for years or even decades. With OA, after your character has reached max level, they can begin amassing treasure and wealth. With it, build kingdoms, hire armies, set up far-reaching trade networks or even construct behemoth weapons of war. The possibilities are limited only by your imagination!

Comprehensive lists: Choose from over 85 weapons, 30 armors, a multitude of expedition gear, siege weaponry, kingdom building materials, starship systems and more. Employ over 50 skills, 70 talents and 125+ magical spells and psionics. Personalize your play style by choosing between 7 different character archetypes, 40+ roles and over 15 races or species, with the option of creating your own.
