Legendary (Game Launcher)

A free and open-source Epic Game Launcher replacement

Legendary (named after the next highest tier in item rarity) is an open-source game launcher that can download and install games from the Epic Games Store on Linux and Windows.

Right now it is in an early public pre-release stage and still needs a lot of work to work. But it does work!

Currently implemented:

• Authenticate with Epic (can import authentication from EGS installation [Windows only])
• Download and install games
• Update installed games (not well tested/potentially buggy)
• Launch games with online authentication

Planned:

• Better Linux and WINE support
• Importing installed games from the EGS launcher
• PyPI distribution
• Miscellaneous optimizations
• Simple GUI for managing/launching games
• Lots and lots of bug fixes and refactoring...

Requirements

• python 3.8+
• requests

How to install

• Windows (standalone): Download the latest EXE from GitHub
• Linux/Windows (requires setuptools to be installed): python3.8 setup.py install

A PyPI package will follow once it has gotten more testing.

The Windows .exe was created with PyInstaller and will run standalone without python being installed.
