## What it is
Crystal is the official open-source C# server and client engine for The Legend of Mir 2, maintained by the LOMCN community. It recreates the 1999 MMORPG's gameplay systems with modern improvements, a modular codebase, and accompanying map editor and database tools.

## Use cases
- run a private Legend of Mir 2 server
- host an MMORPG server and client in C#
- create custom Mir 2 maps and content
- learn how a classic MMORPG server architecture works
- fork and extend a Mir 2 game engine
- recreate the original 1999 Mir 2 gameplay

## When to choose
- you want to run or develop a Legend of Mir 2 private server
- you need a fully managed C# MMORPG codebase to build on
- you want community support via LOMCN wiki, forums, and tutorials

## When to avoid
- you need a general-purpose game engine for new games
- you require a permissively licensed codebase (GPL v2, no explicit license file)
- you are building a modern 3D or non-Mir game
