I've been smitten by Dark Sun as a setting for a while now, and I think I have the gumption to run a short Dark Sun campaign for my D&D group but I can't decide which edition to run. We've played exclusively 5e for our other campaigns, but have been meaning to branch out into other editions. I would just run the rumored 5.5e supplement that's in the works but the UA feels like it doesn't really understand Athas. Anyone have experience running both 2e and 3.5e Dark Sun, and which one would you recommend for a gaggle of 5e normies?
