## What it is
RPGJS is a TypeScript framework for building 2D browser-based RPGs and MMORPGs from a single codebase. It provides RPG-specific runtime pieces such as maps, events, inventory, GUI, save/load, and an authoritative server with client prediction for multiplayer modes.

## Use cases
- build a 2D RPG in the browser with TypeScript
- create an MMORPG with synchronized multiplayer rooms
- make a browser game with maps, NPCs, and quests
- add multiplayer to an RPG without rewriting gameplay code
- build a pixel-art web game with inventory and skills
- run the same game code as standalone RPG or networked MMORPG

## When to choose
- you want RPG-specific abstractions (maps, events, inventory, GUI) rather than a generic engine
- you need a clear client/server architecture for an MMORPG with authoritative state
- you prefer TypeScript and a Vite-based web workflow
- you want to ship a browser-playable 2D RPG quickly

## When to avoid
- you need 3D rendering or a general-purpose game engine
- you are building a native desktop or mobile game outside the browser
- you want a visual no-code editor only (the engine is code-first)
- your game genre has little overlap with RPG mechanics
