I am not tired of any setting really. I just received the 5e Eberron setting book and I like it quite a lot....but.
I feel like setting books since WotC took over are too novelized. (Or too dry like a textbook I’m not quite sure) 200+ pages that I don’t want to read. I would honestly prefer a setting book in the 16-32 page range. FWIW the Expert Rulebook from BECMI is as close to perfect as I have seen.
The Greyhawk Gazeteer was a good size but it lacked a few things namely a couple of decent functional maps. Also some important or unimportant NPC’s.
If they happen to make a book like that for any locale and setting I am likely to buy it. (But I am a grognard not a publisher so what do I know?)
