Magic in stories, I think, always deserves to be treated as something thematically meaningful. What it is and how it works in a setting deserves some consideration. If magic is just a Thing You Can Do, I tend to lose interest.
This is a big part of why I love The Sword, the Crown, and the Unspeakable Power. The Unspeakable Power, whatever form it takes in your session, is the source of magic for all player characters and it has a will of its own. How you use it and what you sacrifice for it matters a LOT.
In R Scott Bakker's The Second Apocalypse series, the metaphysics of sorcery is deeply tied into the existential struggle of the characters. Similarly so with Erikson's Malazan series.
idk man magic should be more meaningful than a weird gun you shoot by wiggling your fingers.
