I recently switched to 100% pirated games (I own copies) on a permanently offline Win10 box. I started to enjoy gaming again when I did. Everything just works, no bullshit.
Previously I used Steam. I have ~700 games in my library. I now purchase from my phone.
That being said. This is a Microsoft forced solution. I refuse to use Win11 or online Windows anything.
Epic, which used to receive my business, changed the privacy rules to access my purchases and was blacklisted on my network as a result. Sunk cost be damned.
Anything can be replaced. Epic went out of their way to be blacklisted and Steam did not.
