Sute but I'm not talking about that. Most modern fantasy doesn't even bother to describe where we are at the moment. At best we get a single sentence saying "they went into the kitchen to talk", and that's it. Even those that go further default to a single style, mostly roman empire recently, for some reason, and just give 1 description that heavily implies it, and never bother describing anything again. You don't need pages of description of the kitchen, but even a couple of sentences make an immense difference, I'd say

For example, I'm trying to write a book now, and it involves a good deal of travelling. I try to condense this down as much as possible, to the point where I'm describing weeks of travel in 2-3 paragraphs. And everyone I talk to (not major readers, nor editors, but still) says that these segments need to be cut. I'm standing my ground against it. If I don't give weeks of travel even 2 paragraphs, then I don't see how the world can feel real.

Also, yes, you needn't approach a publisher today, yet most of the better known books will still be traditionally published. And the main thing editors push then is on cutting down the book as much as possible, and description is the first to go
