Apple Arcade is still going and getting plenty of releases. I don’t know anyone buying it specifically but including it in Apple One (competitively priced subscription for most Apple services) means lots of people have access to it. Me and my partner use it a lot. It’s very nice knowing that those games won’t try to shove microtransactions down my throat.
Aren’t those Snapdragon chips used in Windows ARM computers as well? Also, M-series chips are based off A-series so they’re not that different really.
