As I've posted previously, I disagree with that sentiment.
However, I would be happy if a thousand weird planetary romance settings bloomed. For any of you looking for such settings, here are some I've encountered over the last several years*:
*Disclaimer: some of these push the boundaries of good taste. Also, none of them quite their own brand of weird and sundry influences in the way that Dark Sun is.
@gorice perhaps you could share some additional planetary romance settings that might help fill that Dark Sun sized void.
Yes, I could see a 'spiritual successor' to Dark Sun as being a good thing.
I also think there's a lot of cool things they could do with a time jump. I've proposed ideas for one in prior threads, so I'll just quote myself here:
With all of that, they can have made dramatic
IN SETTING changes to the social structure of Tyr, Raam, Balic, Draj, and Gulg, while describing Urik and Nibenay as cruel vestiges of the old order, and possibly treating Urik as a sealed off North Korea that doesn't substantially interact with the outside (that's how it's described in Beyond the Prism Pentad).
I don't think any of that would make it not Dark Sun--the planet's still dying of magical defilement, the desert is still deadly, the tablelands are still filled with OP psychic monsters and murderous water-stealing bandits, and the cities are still (mostly) run by cruel petty authoritarians.
