I heard Curse of Strahd was good. (I haven't played it yet.) That proved people wanted Ravenloft. So, Greyhawk? Planescape? Dark Sun? Eberron? We'll see how 'off the beaten path' they go.
Err that path is quite beaten!

Another good comparison is the two premier Arch Mages of the setting. Elminister is a HUGE figure in the setting. He hobnobs with gods. Virtually every single major event in FR has his fingerprints on it. Compare to Modenkainen. What has Mord actually done? He doesn't talk to gods. He doesn't play around with massive, setting changing events. He's just kinda there. Inscrutable. Very powerful, to be sure, but, hardly playing in the same league as Elminister.
Birthright, Eberron, Nentir Valley, Rokugan, Jakandor, Ghostwalk?
I have to say something very controversial, but I do say it as an old-timer with much love for both Faerun and Oerth:
Greyhawk really isn't that different from FR.
Difference in level of detail? That's really not a big difference. Liches with armies? Both have 'em. Mad reclusive wizards? Check. Secret racial supremacist organizations? Check. Big waterfront town that dominates the setting and the region's trade? Check.
Much as I love Oerth's history, and its Leiber- and Howard-esque origins, I don't think you could draw a hard line between the two and show a huge self-evident difference.
Dragonlance would be in a different boat, though a slightly similar boat. At least we had the Cataclysm and the divine isolation, and the magic moons, and the LotR-esque elements, but still somewhat classic fantasy.
Dark Sun is an example of self-evidently different. The minute you're fighting with a bone sword back-to-back with your six-armed insect-man ally, against a tribe of cannibal halflings, while your party wizard is sucking the life out of the ground and giving you body aches in the process just to cast magic missile, you KNOW you ain't in Faerun anymore.
Eberron is another - golem-men detectives interacting on lightning trains with good-aligned blood-priests while solving a whodunnit before going home to his two-mile-tall Mega-City while his friend with the inherited magic tattoo cuts a trade deal with a medusa diplomat from the next-door monster nation, that also screams a different brand of fantasy.
Much as I'd like to see Greyhawk goodness, and find out if Iuz still has his nation, or see a mega-adventure dealing with the mystery of the Invoked Devastation and Rain of Colorless Fire, it doesn't scream "drastically different fantasy" from Forgotten Realms to me.
