Yeah one of the reasons I decided to take the plunge and install Linux on my macbook is the compatibility with 32 bit games (risk of rain in particular).
As I have a M1 MBP I am probably going to have to have a separate gaming laptop, or possibly Steam Deck in the future, for quite some time.
Or AsahiLinux might let you keep using your M1.
Work bought me an M1 laptop. I bought a Steam Deck. Paired with my PS5 and Switch, I haven't found a game I _want_ to play that I can't. For AAA titles, I can play them on PS5, indies on the SD, and Zelda on the Switch.
