Choose based on game type: Phaser for full-featured 2D games, PixiJS for 2D rendering and UI, Three.js for lightweight 3D visualization, and Babylon.js for full 3D engines with physics and XR support.

Phaser is a full game engine with built-in physics, input, and scene management, making it suited for complete games. PixiJS focuses on fast 2D rendering and works better for custom engines or UI-heavy experiences.

New projects should use WebGPU with a WebGL fallback, since WebGPU reaches roughly 73% of global users across Chrome, Edge, Firefox, and Safari. Detect support by checking navigator.gpu before initializing the renderer.

Browsers block audio until user interaction occurs. Create the AudioContext on the first click or tap, and resume the context if it is suspended before playing sounds.

Compress textures with KTX2, models with Draco or Meshopt, and audio with WebM/Opus. Load only core assets under 2MB at startup, stream gameplay assets on demand, and prefetch upcoming content in the background.

Yes, a web game can run offline as a PWA by adding a service worker for asset caching, a web app manifest, and serving over HTTPS. This also enables home screen installation and fullscreen mode.
