Jovian Chronicles is a science fiction game setting published by Dream Pod 9 since 1997. It introduces a complete universe for role-playing and wargaming space combat featuring mecha, giant spacecraft, and epic space battles.
The Jovian Chronicles setting was originally published as a pair of licensed supplements for the Mekton role-playing game; Ianus Publications released two volumes—Jovian Chronicles and Europa Incident—in 1992. This first edition is known amongst fans as the "Green Edition" because of the color scheme of its cover design.
After Ianus decided to split into two ventures in 1995 — Protoculture, which would publish Protoculture Addicts magazine; and Dream Pod 9, which would design and market miniatures and gaming books,[1]: 271–272 Jovian Chronicles was re-published as a full-fledged game line in 1997 by Dream Pod 9, this time using their own in-house rule system. This edition, because of its white cover, is known as the "White Edition", and subsequent supplements are also called this, even though several of the supplemental books feature a dark blue starfield cover.
