Ronin Roundtable: Charting the Expanse

As you may well have heard by now, Green Ronin Publishing has licensed The Expanse science fiction novels by James S.A. Corey to produce The Expanse Roleplaying Game, an AGE System game set in the world of the popular series (the seventh novel, Persepolis Rising, was released on December 5th, in fact). The Expanse is one of a number of different AGE System products we’re working on, including Modern AGE, the modern action-adventure equivalent of our Fantasy AGE rulebook, and Lazarus, based on the comic book series created by Greg Rucka and Michael Lark (soon to become a television series as well). Just how are we handling The Expanse in relation to what has come before with the AGE System and what is currently in the works?

Green Ronin to Produce The Expanse RPG

First and foremost, The Expanse is a stand-alone game. It will share a common system with other games, making it easy for AGE System veterans to pick it up. The core book will be self-contained and all that you need to get started playing your Expanse series, much the same way Blue Rose is a stand-alone game, even while it shares systems in common with Fantasy AGE.

Second, while The Expanse uses most of the common elements of the AGE System, our design philosophy has always been to tailor the system to suit the setting and story rather than the other way around, so the game will feature elements particular to The Expanse novels, setting, and style, such as replacing the Health score with a Fortune score, measuring more of a character’s luck in terms of staying alive in a fight or other dangerous situation. A twist on Fortune is you can spend it on things other than damage, but you run the risk of not having as much of it when you’re attacked or encounter other hazards. Likewise, the spending of Fortune affects “the Churn,” an in-game measure of how perilous and complicated things are: Eventually, the Churn can boil over and—as fans of The Expanse novels know—things can get really complicated really fast.

Third and final for this preview, The Expanse core book starts out with a setting in the nearly year-and-a-half between the events of the first novel, Leviathan Wakes, and the second, Caliban’s War. It is after a significant shake-up in the solar system, when major events are beginning to portend even larger changes in the future. It provides us—and your Expanse game—with a convenient starting point without the need to detail every event in the entire series. Plus it allows you (and us) to follow along with the series as major events continue to unfold. You can play in parallel to the events of the novels (it’s a big universe, after all, with a lot going on) or put your own characters into the roles of the crew of the Rocinante in some of the later stories of the series.

We’re still in the early stages of development, working with initial drafts of the text for The Expanse core book, so we’ll have more previews and news for you as things develop. For now, our goal is to ensure your own stories in The Expanse are exciting, fast-paced, and character-driven, with plenty of complications and a universe where even the sky isn’t a limit for very long.
