I started my Linux journey with Ubuntu, then switched to Linux Mint for a while and dabbled with Manjaro for a hot minute, and ultimately found my home on Fedora Workstation for the past several years. Once set up with rpmfusion and 3rd party codecs it’s a very solid and reliable distribution. The new atomic projects (and derivatives) look very interesting too.
I too was surprise to read the actual number being so low considering how much it’s talked about. I never really saw the appeal as steam is pretty easy to get set up and running on any mainstream Linux distro with little fuss, but I recognize it was set up for newbies who want an gaming ready experience. It’s an interesting project regardless.
