main VS HeroicGamesLauncher

Best place to start is to get rid of all the layered packages (RPMFusion) on top of the immutable image then swap to the ublue-Nvidia images that have all the codecs and Nvidia drivers built into the image itself.

If you're using Nvidia I'd recommend using Fedora Kinoite with the ublue-Nvidia image that comes with the Nvidia drivers pre-built in. That eliminates a big chunk of issues with their drivers which is just building the damn things. AMD and Intel drivers are built into the kernel and require zero effort.

What you are looking for is UBlue, https://github.com/ublue-os/main.

It's a variant of Silverblue with Nvidia drivers built in.

If you're using Nvidia, then install using the ublue Nvidia image which has the drivers built in, cause they can be a prick to manage otherwise.

What these sort of introductions to immutable always fail to consider is the other side of the coin, image-based. I'm working on https://universal-blue.org/ along with many people much more skilled than me. We build OCI container images on top of vanilla Fedora Silverblue & many other editions with different desktops. Those images can then be booted to (or rather rebased to) using rpm-ostree. This is a more robust way of extending the system than layering, and the same changes can be easily benefited or inherited from by anyone. You can even make your own image really easily!

I think that VanillaOS and SUSE are working on similar things, but we're not an OS project, just a downstream from Fedora. Fedora's full support is underway but with what's already working perfectly our methods are already IME some of the most robust and easy ways of delivering Nvidia drivers for example.

Heroic Games Launcher: Support is limited to Epic, GOG and Amazon but the advantage is that it can manage their games itself without the need of their own launchers. Doesn't have support for tags currently.

For "normal" games you could look yourself using ProtonDB regarding every game released on Steam and AreWeAntiCheatYet for most multiplayer games. If a game isn't available on Steam you have three possibilities. First if it's available on GOG, Epic Games or Amazon Gaming, you could use the Heroic Games Launcher. Second you could try to run the launchers through Steam itself using once again Proton. Third you could try installing it with a script or tutorial in Lutris or Bottles.

Maybe also look into HeroicGamesLauncher and how to install it, Steam isn't the only platform for gaming and HeroicGamesLauncher help with the following platform: GoG (Good Old Games) and EGS (Epic Game Store).
