Space 1889 (Heliograph reprint edition), softback roleplaying game, by Frank Chadwick
“Role-Playing In A More Civilized Time.
Everything Jules Verne could have written.
Everything H. G. Wells should have written.
Everything A. Conan Doyle thought of, but never published–because it was too fantastic.
Everything you need for adventures of the century.
This rulebook is the heart of the Space:1889 role-playing game. It contains the complete role-playing rules, plus the exciting background of Victorian science fiction: ether flyers and Martian cloudships, the canals and civilizations of the red planet, Venus’s swamps and dinosaurs, the honeycombed interior of Luna, and the thrills of inventions and inventors — the driving force behind Victoria’s multiworld empire! It also includes the errata and additional rules from the Space:1889 Referee’s Screen.”
