I'm a big fan of the incorporating cosmology into the world approach myself. It is much more fun for gods and demons to inhabit the world itself, rather than be isolated off in weird alternate realms of existence that can only be accessed by certain high-level spells. If nothing else, I prefer planes that overlay over the physical world (like the Feywild or Shadowfell) over infinitely-sized theme worlds like most Outer Planes tend to be.
Certainly, each setting really should have its own cosmology. I think it was a big mistake of older versions of the game to even establish a singular cosmology. The Realms, Eberron, Dark Sun, and others really need their own cosmology, if they even need a cosmology at all.![]()
I agree with the idea of richly building cosmology into the world and each world having its own cosmology. I also dislike retconning of worlds to fit cosmology, gods or races. But there is a tension between building cosmology into the world and having different worlds in terms of the rule books. The question is what makes it into the core rules - is it going to be a list of options, a broad assumption, a assumption based on the history of the D&D game or no assumption.
