I don't focus on the sciency and mathy parts of the world building. I can't. I don't have the mind nor experience for it. Where I do focus is on legal systems, governments, and certain social structures. But that is because those are in my wheel houses. Even my magic systems are pretty middling so far as detail goes. Except for my one magic system based on property law, but that's a different story.
However, whenever I do focus on an element of world building it will have a direct impact on the story or characters. I ignore anything other than that because it's a waste of time and I prefer to write stories and interesting characters doing interesting things.
Everything that was said here is exactly how I approach world building.The scientific aspects aren't important to me, because it's a fantasy realm. I can do whatever I want in that regard. I just choose not to focus on it. I care more about the sociological aspect of world building. Languages, the lands, history, government, all that fun stuff.
