I think it’s you who is missing the point everyone is trying to explain to you. Valve doesn’t dictate the price on other stores, want proof? Epic gives free games regularly, those same games are sold on steam, for example currently you can get Definitely not fried chicken for free on Epic, but it has never been free on steam.
Valve only forbids you to sell Steam keys cheaper than on Steam. And even then they tend to turn a blind eye to stuff like humble bundle. They provide you with free Steam keys that you can sell and keep 100% of the value, but in exchange you can’t sell them cheaper than on Steam, which just seems like common sense really. If that lawsuit goes somewhere what Valve will do is charge for extra steam keys, or stop providing them, both of which are bad for developers.





If you’re going to use Arch you should use Arch. One of the biggest advantages for Arch is the AUR which can cause many issues on Arch based distros that are not Arch.
That being said, for a media center, if you’re not used to, I wouldn’t go with Arch, Debian is a much better choice since you’re already used to it and should be good for that use case.
