A setting I've been working on forever started this way, but as I got older I realized it accidentally made a lot of cultures non-human only which felt really gross once I thought about it. I'm now coming up with ways the setting can have people of every real world race represented in every culture and corner of the world, and leaving the fantasy races to be their own things.

I think mostly just making a fantasy world resemble earth is just a very easy shortcut in making a believable world.
