I would like to see what folks could do on DMsGuild with some of the settings not likely to see new versions anytime soon. Being one of those kids that was introduced by way of BECMI, I would love to see community efforts on Mystara.
I also want them to open up Gamma World, too, but that's never going to happen. As someone that worked on a version of Gamma World, I would LOVE to get my hands on it as a DMsGuild creator.
Never say never . . . they certainly could and might, someday . . . but, yeah, I wouldn't hold my breath.
Tricky part is for Gamma World, Star Frontiers, and other "sister" games to D&D . . . do they open up the rules content for those games? Or just the setting material? They might not want alternate rules systems on the DM's Guild, and might feel that allowing Gamma World setting material but only using D&D 5E rules might not work well.
