I've recently go back to Linux (after >10 years), and so far I've only noticed that touchscreen works better on Wayland and that you can scale UI in smaller increments. Otherwise they behave pretty much the same.
Does that mean that you can't listen to the music in the arcade? If so I am impressed that I can read that, as I don't know any German, except few words.
Just look up consonant and vowel charts here, you don't need to study the details unless you really need to. Especially given that this article is full of linguistic jargon, and you probably won't be able to understand any of this unless you have elementary knowledge of phonetics/phonology.
I like how they end support for OS without providing an upgrade for a lot of people. Might as well put a Linux ad in their "Your PC is not supported" bullshit.
