Lutris
Lutris is a Linux gaming app that provides installers for games not available on Steam.
You can also install game launchers like the Origin Client, Battle.net, and the Epic Games Store through it. Lutris also lets you import game launchers from various sources, such as GOG, Humble Bundle, and Steam, so that you can have your whole game library in one place.
Installing Lutris
Installing a game through Lutris
Select the source where you want to install the game from on the left side. For example select GOG if you want to install a game from GOG.
If you want to use an install script from Lutris, select Lutris and click "Community Installers".
Then, in the top bar, click "Search games" and put in the name of the game you want to install, click on it, and click "install" on the bottom left side. After that, just follow what's written on the screen.
Example
Let's install Overwatch.
- Search 'Overwatch' in the "Search games" tab.
- To-do: more steps once you can upload photos to the site
Runners
A runner is a method to start your game. Lutris supports several runners: Linux, Steam, and Wine.
Linux is for native games, and Steam is for Steam games. I advice using Steam to run Steam games. This is probably easier (This is the personal opinion of the author).
Wine is what you want to use for every other game.
