I'd like to go watch it, but they apparently forgot countries outside the US exist...

There is also a sequel coming! https://store.steampowered.com/app/2900640/TOEM_2/

No. Delisted from sale just means people can't buy new copies anymore. It happens to virtually every game that features licensed music and/or brands, once those licensing deals expire the game can no longer be sold. However, if you purchased the game before that happens, it's still in your library and you can still download and play it as normal. Usually delisting is also followed by shutting off the respective game servers soon after, but as far as I know online services for FH4 and FH3 are still up. Because I purchased those games when they were available I can still play them, and even when the servers go offline they have offline functionality that remains playable.

If I'd go with a Forza horizon, which one should I pick?

I mean 5 is the only one available right now lol. 6 isn't out yet, and every older title has been delisted from sale due to expired licenses.

The Forza Horizon Games all work great on Linux, but in case of doubt you can of course always check ProtonDB

They're lying or somehow completely misinterpreted what they saw in game. At no point did they lock base game content behind another paywall.

Couldn't you theoretically download an ISO for an older version of Win 11, install that offline without an account, then update it to the latest version?

There are some android based handhelds in the 200€ to 350€ range that can play a lot of emulated stuff as well as a solid number of PC indies/older titles through translation layers.

You can also grab a Retroid Pocket 5 and install Rocknix Linux on it if you want to avoid android, but it'll be more limited when it comes to playing PC games until the modding community figures out how to incorporate valve's arm translation layer.

I don't mean to undermine your efforts OP, just pointing out it exists:
