There are over 89 titles (some are Game Engines) native to MacOS currently for Sale for only U$10,00 on Itch. The bundle is raising money to help with the fire in California.

Many of those games and software is not available on Steam (or anywhere else I know) and they're really well polished.

I'm not sure if they run on ARM (Mx chips) or only on x64 (iX chips). Check that for yourselves!

It will last until the 13th of March 2025, so check that out if you want a larger library of games for your Mac.
