Lutris the Open Source gaming platform for any Linux distro.

Lutris is an Open Source gaming platform for Linux. It installs and launches games so you can start playing without the hassle of setting up your games. Get your games from GOG, Steam, Battle.net, Origin, Uplay and many other sources running on any Linux powered gaming machine.
You need to create an account and you can run many games on Linux and multiple platforms, see the official website with games.
If you want to install it with your Linux distro the take a look at the official webpage.
I used the installation process on Fedora 31 with DNF tool:

[root@desk mythcat]# sudo dnf install lutris
