The Importance of Going Deep With Magic Systems

When I'm developing magic for a story, my primary goal is to say how is it going to affect the characters and the conflict? That's where I'm going. But I also want to say, all right, how is the culture adapted to this magic? How have different cultures adapted to this Magic? What, by changing some fundamental laws of physics, what have I done to how science is going to progress? And all of these different things, if you are doing a magic, asking yourself these sorts of things will honestly make your magic in your world feel much more fully realized than just adding a ton of new things.
