Set in the 69th Century, the series allowed gamers to play out the battles between the "Terran Overlord Government (TOG)", a corrupt galactic empire, and the "Commonwealth", an alliance of humans and aliens. The focus of the plot, like with many strategy games, is to present a long term conflict to enable as many individual situations and environments as possible. Most of Renegade Legion deals with large, military battles to be played on hexagonal grid mapsheets in a turn-based rules system.
