Someone already did that - might have been called Red Dawn or something like that? The kickstarter was, if i remember right, successfully funded and working on stretch goals, when it abruptly got yanked and as far as i know no explanation was forthcoming. Strong suspicion is that there was some sort of legal measure taken by WotC who saw these guys flying too close to the sun, copyright-wise.Or perhaps some enterprising 3PP sets out to do a "Shrouded Star" retroclone that deliberately evokes the style of Dark Sun. Which both frees them from having to be completely faithful to the original and allows them to do a Mature Gamers imprint instead of D&D's mandatory All Ages rating.
Mind you, they'd already run into some thorny territory on the more difficult aspects of old Dark Sun - their description of their faux-muls as 'ideal slaves' raised a few eyebrows, for instance. And they only twigged to the need for a sensitivity reader quite late in the process, which was a worry. Surely if you're doing a Dark Sun reboot/tribute/ripoff/sequel in 2023, this is one of the FIRST issues you think about?
