Oh I’m sure they can justify spending the time porting the game. I just can’t blame them for not doing so when Apple’s policy is to not give a shit.

Yes, but it’s highly unlikely they can reuse that effort. TF2 uses an older version of source, so you either end up having to update everything to a newer version or redo all the effort you’ve already put in to porting source, but for an older version. Now multiply that by the number of source games.

I can see how you might come to that conclusion, but porting to 64bit is way more involved than it may seem. x86-64 is different enough to x86 that you’re basically porting to a new architecture: all your assembly will break just like it would porting to arm. On top of that all your sizes have changed and caused all sorts of bugs, for instance: long is 4 bytes under 32 bit on all platforms, but it’s 8 bytes on macOS & Linux and 4 bytes on Windows under 64 bit.

It’s mind boggling that Apple would drop 32bit support. Adding 64 bit support can be a lot of effort, especially on older code bases, and there’s a whole bunch of games that’ll never receive updates again. You could’ve had arm32 support, with the ability to run any x86 games.
