Do those games run on the current macOS (Monterey) and with M1? I remember having Steam on my 2018 Intel Mac mini and when I upgraded to Catalina it dropped 32 bit support so that meant a lot of old games that were no longer being updated stopped working. I haven't tried anything other than WoW on my iMac.
Well, there you go. A failure of preventive maintenance on your part where it touches on OS updates would have saved you a lot of headaches and stress. It seems like you and I saw Catalina coming from a mile away, knowing that the 32-bit culling was coming. The difference between us was that I took it as a warning to keep running Mojave, whereas you updated anyway, yes?
Also, you asked about websites that constantly update us on Mac games that run on MacOS natively, Rosetta 2, via Crossover, or Parallels.
There is such a site.
You should check it out. It’s run by Andrew Tsai, who’s also very prolific on YouTube and Discord.
If you weren’t aware, there is another site run by a developer named Schnapple, called Mac Source Ports, where you can find Apple Silicon-native games going back to the 1990’s.
