Apple’s fourth-generation Apple TV offers an App Store chock full of third-party apps for you to enjoy—including, yes, games. To expand the gaming universe further, the Apple TV is supporting Apple’s Made For iPhone (MFi) standard for third-party controllers, which means you’ll be able to game with a Siri Remote and Xbox-style controller alike.

So, how do third-party controllers work in the wide wonderful world of tvOS? We’ll walk you through it so you can start gaming in no time.

One thing that struck me in particular:

All games on the tvOS App Store offer a helpful indicator on their app pages in regards to controllers: If your game offers third-party controller support, you’ll see Game Controller Optional below the description.

I do find that wording interesting—”optional”—given that, currently, Apple prevents tvOS games from requiring a game controller. It might be worded in such a way to open up the possibility controller-required games in the future… or it just might be a random word choice on the part of tvOS App Store staff.

Great job, as usual, from Serenity.
