Apple TV gaming could support third-party controllers
We’d assume you’d like to try gaming on the new Apple TV. But using a remote control is a bit weird for gaming. You do have the option use third-party controllers because you connect them via Bluetooth. However, it might be a bit more complicated since any third-party OEM has to pass Apple’s MFi program. Right now, when you look at Apple’s gaming page for Apple TV, you see Steelseries controllers. Hopefully the options increase as time goes on though.
