For what it’s worth the Magic Keyboard is very expensive for gaming and has a tiny trackpad I wouldn’t want to use for gaming. So you’re keyboard + touchscreen at that point, which isn’t ideal. You’ll have a far better experience just using a Xbox/PS5/MiFi controller for a lot less money. I’ve done it, works great.
