Powerful event system and rendering engine
Makie is certainly not a game engine, but its rich rendering and interaction features allow the creation of simple, interactive games such as Minecraft.
While Makie might not be the go-to for more complex games, using it to build a Minecraft-like game highlights its versatility for complex, interactive visualizations.
Many use cases, such as AI gyms or complex, interactive 3D simulations, greatly benefit from this.
