From the introduction:
Loner: Spacer is a solo tabletop RPG adventure set in the vast, uncharted expanse of the cosmos. This game immerses you in the life of a lone starfarer navigating a galaxy filled with dangers, opportunities, and mysteries. Will you become a legendary trader, a daring explorer, or a feared outlaw? The choice — and the stars — are yours.
Loner: Spacer follows the following design principles:
Portable: to play you will need a few common (six-sided) dice and writing materials. Anything else is optional and not essential.
Rules-Light: the game relies on a few rules and only one solving mechanic, easy to learn and eventually to memorize.
Tag-based: characters and situations are defined only by qualitative descriptors and no quantitative characteristics.
With a focus on quick resolutions, Loner: Spacer throws you headfirst into the heart of the action. Your character will be defined by thematic tags, such as “Reckless Pilot,” “Ace Navigator,” “Cunning Smuggler,” or “Starry-Eyed Explorer.”
