Nah, I was more envisioning something like a multiplayer game where each player has spells they can learn by doing certain joystick/mouse/vr controller movements (or whatever), and both those movements and the spells themselves are uniquely randomized as much as they can be. You’d need to discover what you can do, and at least with a group of friends those spells would be pretty unique to you, along with which ones are easier or harder to do. It probably wouldn’t be balanced but it’d be fun.
