Post-apocalyptic D&D world Dark Sun is being revamped in early 2027, and it'll be the first 18+ setting for the tabletop RPG.
There's a good reason for that mature age-rating. The returning D&D franchise (which takes place in a world devastated by magic) is going all in on the gore, sex, and bleak atmosphere of its inspiration. Unlike many of the best tabletop RPGs, you don't save the kingdom in Dark Sun; you're simply trying to survive it.
