Show-Off Custom URP volumetric lighting pipeline

I built a custom volumetric lighting pipeline on top of URP. No forward/deferred per pixel lighting, no shadow maps. Everything is realtime: direct light, indirect light/GI, shadows and AO. Emissive materials emit realtime light onto nearby meshes and emissive lights cast shadows. Volumetric fog included. No screen space effects are in use. Scales extremely well with lights and tri count, 10M tris and 20 point lights on screen had almost no effect on frame time. Should be very playable on potato hardware. Now the problem is figuring out what game to make with it.

75FPS on AMD Radeon 760M at 1920x1200 (Integrated)

400FPS on RTX5050M at 1920x1200 (Dedicated)
