I was planning to reply to this thread along these lines but you beat me to it. The technical details of the settings and what it contains are way more important than the mood and whether it captures my imagination.
For example, I like SciFi, but first way less than heroc-fantasy, and I dislike mixes, they are usually poorly done and an excuse to hide flaws in the fantasy design. Also, for D&D, I like High Fantasy, which is what the setting needs to capture because it suits the design of the game.
These are mood breakers for me.
Exactly ! The combination of a few words, the images, the setting of pages, etc. are for me way more important to fall in love with a setting.
But not only, because it's very much a roleplaying setting. The adversaries are usually way stronger than the adventurers, you can't succeed without cunning, negotiation, roleplay, and especially without dealing with the alien nature of creatures from all corners of a multiverse.
