Best ForQuick one-shots with zero prep: the crew of the interstellar scout ship Raptor must save the day while the captain is out of commission.Hard sci-fi sandbox campaigns with trading, exploration, and realistic space travel.
HighlightsEntire game fits on one page, zero prep needed, character creation takes seconds, free and Creative Commons licensedComprehensive sci-fi toolkit, lifepath character creation, detailed trade/travel systems
ConsiderationsGM carries most of the creative and structural load, single stat means characters can feel mechanically identical, no structured scenario framework beyond the initial hookLifepath character creation can produce unplayable results, subsystem rules are spread across multiple supplements, steep buy-in if using official sourcebooks
