So two of the three remaining are Blackmoor and Mystara, which incorporated Blackmoor.
I know someone earlier decried the last four or five as "generic" settings. But I don't think of them as generic. They may seem generic because of their age, but Blackmoor had high tech in it (fairly typical of '70s fantasy) and so did Greyhawk for the same reason.
Mystara is a hollow planet. Sure, it's inspired by Verne and Burroughs, but that's in keeping with Mystara being inspired by Robert Howard. And it's the only RPG fantasy world I'm aware of that has a hollow planet. Yes, Mystara has elves, dwarves, and halfings but its inspiration is even older than that. In 2017, it seems novel that the setting's inspirations are about 100 years-old.
Hollow. Planet.
