Having recently discovered some older volumes of the Conan stories, collected and added to by L. Sprague De Camp in the Lancer/Ace paperbacks printed during my youth, I have been rereading these edited versions of stories including those penned by original Conan creator Robt. E. Howard, those "finished" by either De Camp or Lin Carter, and those Conan stories written by De Camp and Carter featuring a version of the Conan character somewhat different (more morally ambiguous?) than Howard's depiction of the noble savage.
The influence and impact of the Conan character and stories on the role-playing hobby has been immense. Gary Gygax mentions "Howard's Conan saga" in his 1973 Foreword to the original edition fantasy role-playing game and he and co-creator Dave Arneson are both known to have enjoyed the character. Conan is mentioned on the back cover of first edition of RuneQuest published in 1978. Conan is noted in Tunnels & Trolls as the inspiration for the warrior class in that system.
