The only Steam game in my library that still works now is Myst. The list of Steam games that even supported macOS at all was already quite short, but now Portal, Portal 2, Team Fortress, the entire Half-Life series, and quite a few others will no longer run. The switch to Apple silicon machines also makes running them in a VM tricky. Even though Windows supports running x86 code on Arm hardware, the mix of architectures inside the VM creates new problems, particularly for Steam.
