I use EndeavourOS (which is almost the same as Arch) for gaming and it works great.

You can do .net on Linux but Windows is much better for that. I recommend using Windows for work and Linux for everything else.

I recommend going with Virt-manager, it works much better than VirtualBox in my experience.

I use Heroic games launcher for Epic and it supports GOG too.

It works, thanks.

Around 1 and a half years.

1. I never used Wayland but Xorg works really well.

2. Don’t copy terminal commands from internet if you don’t know what they do. Also, try new things just to try them. That’s how I started using many things that now make the core of my computer experience. Even if something looks scary I recommend giving it a go because in most cases it is much easier than it looks (at least when you have some experience with Linux).

3. YouTube can be a good resource at the start.

4. Switching to Linux was very smooth experience for me because I wanted to inform myself about Linux before switching just to know what I’m getting into. If you go prepared you probably won’t experience many problems.

Problem I have with Flatpak is their way of naming packages which makes them very akward to run in a WM. That’s basically the only reason why I haven’t used Flatpak since I switched to WMs, pacman and AUR also work really well so there isn’t even a reason to use something else.

To be fair, I would see why. Arch isn’t that hard to install anymore so some people see Arch-based distros that are just Arch with GUI installer as useless. I use EndeavourOS just because GUI installer is more convinient to me.
