@psilocervine I beg to differenciate:
It's just that for #IndieDevs #Marketing is the key to success.
Obviously it doesn't make sense to do a #macOS-exclusive:
Some games did #iOS-exclusivity due to lower #Piracy rates than #Android.
#AppleArcade is a working way to squeeze revenue out of an old title that is is the sub-$1 bargain bin at Steam and where everyone has closed the books on as in 'nice to have some revenue, but we ain't do much more about it' without going #PayToLoose or shoving it full of #ads and "#Microtransactions"...
I'd say if one's already using a multi-platform-engine then clicking "export to #Mac" is an option.
