Yeeeah, for a fresh Bazzite install I'd agree that "swap Lutris for Heroic" is solid advice.

In Bazzite flatpak is the way so much that you will open Discover and only see flatpak, so if this was really, really beginner tips I'd suggest not learning what any of that means for as long as possible and just relying on Discover for your apps until you hit a roadbump. This guy seems well informed enough that is not a problem, but hey.

I'm also mildly annoyed that ujust is important enough to still need that terminal splash screen but not enough to be baked into the config tools by default in GUI. So weird.

That's either another thing you should try not to learn about if everything works fine out of the box or something you really should look into if it doesn't, and that's not great.
