I'm talking about the genre of S&S as represented by the stories of Conan, Elric, Fafhrd & the Gray Mouser, and so on. I don't mean official variants of those IPs, but games that evoke the traditions of those works. A great example of a variant ruleset for S&S of years past is the Conan RPG put out by Mongoose for 3e in 2003. It made many rule additions to the existing 3e core that really worked in service of the setting. Is there a S&S variant for 5e, regarding of whether it has a campaign setting? I'm thinking of creating one of my own, but I don't want to duplicate something.
