Unlike the regular App Store for iPhone, iPod touch and iPad application, a brand new tvOS App Store for Apple's latest fourth-generation Apple TV makes it easy to distinguish at-a-glance between games that offer support for 'Made for iOS' (MFi) gamepads and game controllers and those that don't.
As first observed by AppleInsider over the weekend, not only does the device's App Store storefront app clearly states whether or not a game supports dedicated MFi game controllers, but compatible controllers can be used to navigate across the entirety of tvOS.
