Granblue Fantasy: airships, sky islands, big dumb evil empire, brand new races (that are actually just classic races with a twist) and an interesting new kind of magic (jrpg-style summons - basically super spells you get as quest rewards).
Ivalice, home of many Final Fantasy games and Vagrant Story.
I want a Riskbreaker and Dragoon fighter. I want to adventure in Léa Monde underworld to stop an evil mage's plot. I want to adventure in Ogir-Yensa desert or the Necrohol of Nabudis and shop in the streets of Rabanaster.
I want stats for Seeq, Viera, Moogle, Banga and Mu.
Then, by all means, give me setting books expansions for smaller setting like Spira, Eos and Cocoon/Gran Pulse.
The world of Titan from fighting fantasy games, I know it probably counts as just another generic fantasy setting, but I loved those books growing up. It probably wouldn't be that hard to use as a setting now. I had all the advanced fighting fantasy books as well as the Titan world book back in the day, some of my favourite books ever.
