Apple’s iOS and iPadOS 13 support multiple PS4 or Xbox One controllers, which could be huge for Arcade
Apple's iOS 13 update (and the newly-renamed iPadOS for iPad hardware) both support multiple simultaneous Bluetooth game controller connections. Apple added Xbox One and PlayStation 4 controller support in the updates, and after doing some digging, I can confirm that you can use multiple of either type of controller on one iOS device running the update, with each controlling a different player character.
That's the good news: The bad news is that not many games take advantage of this right now. I wasn't able to find a game in Apple's new Arcade subscription service to try this out, for instance - and even finding a non-Arcade iOS game took a bit of digging. I finally was able to try local multi-controller multiplayer with Horde, a free-to-play 2-player co-op brawler, and found that it worked exactly as you'd expect.
With Arcade, Apple has done more to re-invigorate the App Store, and gaming on iOS in particular, than it has since the original launch of the iPhone. The all-you can game subscription offering, which delivers extremely high-quality gaming experiences without ads or in-app purchases, has already impressed me immensely with the breadth and depth of its launch slate, which includes fantastic titles like Where Cards Fall, Skate, Sayonara: Wild Hearts and What the Golf, to name just a few.
Combine the quality and value of the library with cross-play on iOS, iPadOS, Apple TV and eventually Mac devices, and you have a killer combo that's well-positioned to eat up a lot of the gaming market currently owned by Nintendo's Switch and other home consoles.
Local multiplayer, especially on iPads, is another potential killer feature here. Already, iPad owners are likely to be using their tablets both at home and on the road, and providing quality local gaming experiences on that big display, with just the added requirement that you pack a couple of PS4 or Xbox controllers in your suitcase or carry-on, opens up a lot of potential value for device owners.
As I said above, there's not much in the way of games that support this right now, but it's refreshing to know that the features are there for when game developers want to take advantage.
