## What it is
Arx Libertatis is an open-source, cross-platform reimplementation of the engine for Arx Fatalis, a 2002 first-person RPG/dungeon crawler/immersive sim. It fixes bugs, supports modern systems and new platforms, and requires the original game data to play.

## Use cases
- play Arx Fatalis on Linux or macOS
- run Arx Fatalis on modern 64-bit systems
- fix crashes and bugs in the original Arx Fatalis
- play Arx Fatalis in widescreen resolutions
- use the Arx Fatalis demo data to try the game
- mod and customize the Arx Fatalis engine

## When to choose
- you own Arx Fatalis and want to play it on a modern or non-Windows platform
- the original game crashes or has compatibility issues on your system
- you want an open-source engine to build mods on

## When to avoid
- you don't own a copy of Arx Fatalis or its demo, since game data is not included
- you want a modern RPG rather than a port of a 2002 game
