Retro RPG: Warhammer 40,000 Rogue Trader
Warhammer 40,000: Rogue Trader is the first edition rule/source book for the Warhammer 40,000 miniature wargame by Games Workshop.
Created by Rick Priestly, The gameplay of Warhammer 40,000: Rogue Trader differs from its main modern-day descendant, in that it was heavily role-play-oriented, with great detail placed on weaponry and vehicles and the inclusion of a third player (the Game Master) in battles, a role not dissimilar from the Dungeon Master of Dungeons and Dragons. Rogue Trader introduced some races that were later removed from the setting, such as Squats (Warhammer dwarfs in space), Zoats (also present in Warhammer Fantasy Battle) and the Space Slann (a humanoid frog-like race).
