that's probably for the best.

Legendary (Game Launcher)

A free and open-source Epic Games 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.
