Most of these are absolute whiny bullshit. Half of these are about progress. 32 bit app support? Yeah no shit, this isn’t windows. They’re gonna move forward at some point.
If half your library is 32-bit Valve games sure but just because Steam warns you, doesn’t mean it’s broke. As I don’t play any Valve games (CSGO, TF2, etc), the 32-bit games I do have will run just fine on apple silicon. Haven’t found one game in my library that won’t work due to 32-bit.
