Stars Without Number

Stars Without Number is a science fiction tabletop roleplaying game set in a far-future universe after the collapse of human space civilization. The game system combines old-school RPG mechanics with modern design elements to create space exploration and adventure scenarios. The rulebook provides tools for Game Masters to generate sectors of space, complete with planets, alien species, and political factions. Players take on roles as adventurers in this post-collapse setting, using skills in combat, technology, psionics, and interstellar navigation to survive and thrive. The core book includes rules for character creation, spaceship combat, world-building, and faction management. A complete game system is presented alongside setting material that establishes the universe's history, technology, and social structures. The game explores themes of rebuilding civilization from ruins, the cyclical nature of human society, and the consequences of unrestricted technological advancement. Through its mechanics and setting elements, it presents questions about humanity's relationship with artificial intelligence and our capacity for both destruction and renewal.

🎲 Kevin Crawford funded Stars Without Number through his own savings while working as a teacher, initially releasing it as a free PDF which helped build its dedicated following. 🚀 The game's "sandbox" creation tools are so well-regarded that many Game Masters use them for other sci-fi RPGs, including Traveller and even homebrew D&D space campaigns. 🌌 The setting takes place after "The Scream," a psionic disaster that collapsed faster-than-light travel and communication, leading to thousands of isolated human worlds developing independently. ⚔️ The combat system is deliberately lethal, with even experienced characters being vulnerable to well-placed shots, encouraging players to think tactically rather than rely on hit point reserves. 🎮 Despite being a sci-fi game, Stars Without Number uses mechanics inspired by old-school D&D, specifically the 1981 Basic/Expert edition, making it easily accessible to traditional fantasy roleplayers.
