## What it is
FreeOrion is a free, open-source, turn-based space empire and galactic conquest game inspired by the Master of Orion tradition. It implements the classic 4X model (eXplore, eXpand, eXploit, eXterminate) with a scriptable engine that lets the community customize game mechanics and content.

## Use cases
- play a turn-based 4X space strategy game
- run a galactic conquest grand campaign in singleplayer or multiplayer
- customize game mechanics via the scripting engine
- contribute to or fork an open-source space 4X game engine
- build FreeOrion from source on Linux

## When to choose
- you want a free, open-source alternative to Master of Orion-style 4X games
- you need a cross-platform (Linux, Windows, macOS) strategy game
- you want to mod or script custom game mechanics and content
- you prefer singleplayer or multiplayer galactic conquest without DRM

## When to avoid
- you want real-time strategy rather than turn-based gameplay
- you need a game with commercial support or guaranteed maintenance
- your hardware lacks OpenGL 2.1 support or a 1280x800+ display
- you want a lightweight game that runs on unsupported architectures with official support
