Stars Without Number

A d20 based RPG engine with default setting. Something like Sci-Fi OSR.


 * After the End: The setting is at the era of slow recovery after a Terminally Dependent Society lost its cornerstone and was mostly ruined. "The Scream" killed or drove insane everyone with psychic powers worth a damn, which was quite common in humanity (and other major spacefaring species), and as such also turned all psionic dependent devices (most high-tech machinery and information storage) into useless souvenirs and disabled interstellar travel. New generations of psychics emerged, but without correct training they tend to die or go insane before becoming useful. Even after this issue is solved, there are fewer of them, not anywhere as well-trained due to lost knowledge, and after being burned once, nobody considers such abilities reliable any more, so everything that required a psychic user has to be converted to less arcane interfaces if at all possible — once someone figures out how it works at all.
 * Background Based System: A general Background Package per origin, then class adds a Training Package. Together they define starting skills.
 * Character Class: Wide general classes much like Alternity.
 * Hit Points
 * Lost Technology: "Pretech" — non-trivial psitech and all the stuff with lost manuals.
 * Psychic Powers
 * Psitech
 * Standard Sci-Fi Fleet: Hulls come in 9 basic types of 4 size classes.

May have good sensor array and nav computer, dedicated medbay, armory, repair facilities, fuel scoops, cryo pods, boarding equipment, precognitive navigation chamber.
 * Cruisers: Bulk Freighter, Cruiser. — Cannot land, thus need to carry at least cargo lighters to reach planet surface. May carry Fighters. May have hydroponics.
