From Introduction: WORMHOLE X-TREME! Journeys to Other Worlds is a simple to learn roleplaying game expansion to Star Legion 1PG. In it, players take on the roles of explorers, scientists, aliens and soldiers in a TV show in which the characters travel to other worlds, past times, alternate dimensions and parallel realities. It assumes the players and ref already have some rudimentary experience with role-playing. It’s meant to be played in the vein of Stargate, Time Tunnel, Sliders, Dr Who and Time Cop so keep it light (yet adventurous).
