Adding to the Docker chorus. I started using Docker before even using the command line. My route in was to use Unraid but that may not be best for you. I use Portainer in another install but I think the way it handles storage is a bit obtuse. In any case, as many others have said, using Docker is a piece of cake once you understand the basic ideas. Those being that a container is like a portable self contained machine that runs a specific service and any persistent storage needs to be outside the container. Containers are always my first idea when running a service as you know they will work on your system, you don’t have to worry that there will be conflicts or whatever.

You think you know how dumb someone is, but they can always surprise you.

A person of culture, I see.

YMMV of course but I was playing Timberborn just the other day on Mint, on an Nvidia card, through Heroic. Proton seems to have been a gamechanger. I have just made my first steps into switching my daily driver myself. I may have been lucky but all the games I have wanted to play have worked so far. I also have a Steam Deck, which is what has encouraged me that it may be possible.
