## Directory Notes

Stars Without Number is Kevin Crawford's sandbox science-fiction RPG about crews crossing a fractured sector, taking risky jobs, and changing local politics through play. It is often treated as both a complete game and a GM toolkit because its planet tags, faction rules, starship procedures, and adventure generators are useful even when a table is running another sci-fi system.

## Theme and Setting

The default backdrop is a post-Scream future where humanity's interstellar society collapsed and isolated worlds rebuilt in radically different directions. That premise lets one sector hold frontier colonies, cyberpunk city-worlds, lost technology, alien ruins, military powers, and strange cults without needing a single fixed metaplot.

## How Play Feels

At the table, Stars Without Number plays best when the group wants open-ended choices. The GM presents factions, trade routes, patrons, hazards, and rumors; the players decide which problems are worth chasing. Combat can be dangerous, but the game is just as interested in planning, exploration, negotiation, and deciding what kind of reputation the crew earns.

## What Makes It Distinct

The sector toolkit is the main draw. Tags turn planets into adventure engines, the faction turn keeps powers moving between sessions, and the rules make it easy to generate useful detail without writing a novel before play. Compared with heavier sci-fi games, SWN gives the GM more procedural support and asks the table to discover the campaign through action.

## Where It May Not Fit

Skip it if you want a tightly scripted plot, very cinematic resolution, or a game where the setting does most of the work for you. Stars Without Number rewards tables that enjoy maps, consequences, logistics, and the freedom to ignore the obvious quest hook.
