This is Minecraft. Like literally, this idea spawned Minecraft. https://www.wired.com/2013/11/minecraft-book/

VR game. Finger tracking controller mandatory. Basic gameplay is that of a wizard, casting spells. Each finger is an element, like air, water, fire, earth, life. You cast a spell by holding an element and drawing a shape in the air then gesturing. So a fire bolt would be hold fire, move in a line to point the direction, release fire mid throw. To make a fire ball, hold fire, then draw a circle in the air, then throw, release in the throw. Allow the user to make up spell effects by combining elements, shapes and gestures. Combine air and earth, draw a spiral, point at an enemy to trap them in air bands and earth bonds. Paint an ally in broad strokes with life to heal, etc. Moderate inspiration from Wheel of Time, if you’ve read it.

The gameplay of finger-wiggling mage sounds fun. Add bullet time for easy mode/overpowered.

The only piece I think you missed is that nation states and surveillance corps will buy up foreclosed data centers for pennies on the dollar to use them to power a surveillance/police state.
