Could you build this?
Partial Creating standard 3D web spaces with Three.js is vibe-codeable, but handling smooth multiplayer physics, synchronized mini-games, and low-latency spatial WebRTC audio across browser devices requires specialized networking engineering.
What it would actually take: The app requires a WebGL/Three.js or Babylon.js frontend coupled with a real-time WebSocket state synchronizer and a selective forwarding unit (SFU) for WebRTC audio (e.g., LiveKit or Mediasoup). The core challenge lies in maintaining sub-100ms spatialized audio panning, authoritative physics/game synchronization, and graceful degradation across lower-end client hardware without lag.
