## What it is
The Forgotten Server (TFS) is a free and open-source MMORPG server emulator written in C++, forked from the OpenTibia Server project. It implements the server side of the Tibia game protocol, allowing players to connect with clients such as OTClient and providing Lua-based scripting for game content.

## Use cases
- run a self-hosted MMORPG server for Tibia-like gameplay
- emulate a Tibia game server with custom maps and content
- script custom quests, spells, and NPCs using Lua
- host a private multiplayer role-playing game server
- build a custom OpenTibia distribution on top of a stable server core
- learn how MMORPG server internals like combat, pathfinding, and protocol handling work

## When to choose
- you want to run or customize a Tibia-compatible MMORPG server
- you need a mature, actively maintained OpenTibia server implementation
- you want to extend game logic through a well-documented Lua scripting interface
- you prefer a C++ server core with community support on OTLand

## When to avoid
- you need a general-purpose game engine rather than a Tibia protocol server
- you want to build a modern MMORPG from scratch with your own protocol
- you need a client-server stack for a non-Tibia game
- you require commercial licensing or closed-source distribution
