Open Hero Odyssey

Play the next-generation role-playing game!

Get Started

Welcome to Open Hero Odyssey!

Happy 2021!

OHO is a developing RPG platform for both world-building and hero-building that introduces the skill proficiency system, allowing you to select different proficiencies to define your hero's abilities and, subsequently, their role in the party, instead of choosing between classes that force you into a particular role. It's adaptability allows it to be used for any style of play, from fantasy adventure to futuristic space battle, and everything in between.

Open Hero Odyssey is looking for playtesters!

OHO has completed Phase One testing implementation, and I've begun posting updates to the mechanics and rules based on the issues found. (Click here to see the games in progress). Character sheets and dice are replaced by a mobile app (coming soon!) that controls the minute aspects of play, while mechanics are tested (like damage, and certain special abilities), on player and game master side. The goal for players here is to test the limits of the mechanics and rules as they are stated. Min/maxing for this purpose is highly encouraged. The goal for game masters is to get a feel for running gaming sessions with the mechanics, and seeing where problems arise in practice.
