Traveller

Traveller is a tabletop game where characters journey through star systems, engaging in exploration, ground and space battles, and interstellar trading, published in various editions since 1977. The original version, known as Classic Traveller, was published by Game Designers' Workshop (GDW). Throughout the years, the game has evolved, with notable editions including MegaTraveller, Traveller: The New Era, Marc Miller's Traveller, GURPS Traveller, Traveller20, Traveller Hero, Mongoose Traveller, and Traveller5. The current rulesets are Traveller5 and Mongoose Traveller 2nd Ed., both of which draw from the original Traveller rules and rely on six-sided dice.
