## What it is
Ikemen GO is an open-source fighting game engine written in Go that is backward-compatible with M.U.G.E.N 1.1 Beta resources while adding new features. It supports Lua and ZSS scripting, rollback and delay-based netplay, and runs natively on Windows, macOS, Linux, and Android.

## Use cases
- play MUGEN characters and stages on Linux or macOS
- build a custom fighting game with Lua scripting
- play fighting games online with rollback netcode
- run MUGEN content on modern 64-bit systems
- create new game modes and story paths for MUGEN resources
- develop a cross-platform fighting game engine

## When to choose
- you want to run or extend M.U.G.E.N content on modern platforms
- you need open-source, MIT-licensed fighting game engine with netplay
- you want scripting extensibility via Lua or ZSS

## When to avoid
- you need a general-purpose 3D game engine
- you require guaranteed compatibility with every legacy MUGEN add-on
- you want an engine with a large commercial ecosystem

## Facets
