## What it is
BrowserQuest is a deprecated HTML5/JavaScript multiplayer game experiment by Mozilla, featuring a browser-based MMORPG-style demo with a Node.js server backend. It served as a showcase for HTML5 canvas and WebSocket capabilities.

## Use cases
- learn how to build an HTML5 multiplayer game
- study a WebSocket-based game server implementation
- reference for canvas-based 2D game rendering
- example of real-time multiplayer browser game architecture
- starting point for a forked browser MMO project

## When to choose
- you want to study or fork a classic HTML5 multiplayer game demo
- you need a reference implementation of WebSockets and canvas in games

## When to avoid
- you need a maintained, production-ready game engine
- you want active community support or recent updates
- you need modern tooling or security patches
