Apple Arcade will live as a new, separate tab within the App Store, and consist of more than 100 expertly-curated games that will be exclusive to the Apple Arcade service. You will have to pay a monthly fee but will also be able to play any Apple Arcade game for as long as you want and on whatever Apple device you want, be it iPhone, iPad, Apple TV, or a Mac.
There will be no ads and in-app purchases included with any Apple Arcade titles, so parents can be content that their child wouldn't rack up an astronomical bill with power-ups. Parents can also manage Apple Arcade with the ScreenTime feature and limit for how long their kids game.
The best bit? All the games will utilize a continuity-like feature that will let you switch devices and continue from where you left off. Aside from that feature, Apple Arcade will be completely offline and will let you download all the games on your device so that you can game while being off the grid.
Some of the developers and game studios that will be developing exclusive titles for Apple Arcade are Konami, SEGA, Disney Studios, LEGO, Cartoon Network, Devolver, Gallium, Sumo Digital, Klei Studios (Don't Starve, Oxygen Not Included), Finji (Night in the Woods), and many, many others. It became quite clear during the keynote that Apple wants to help game developers create games that would otherwise be swamped within the hordes of free-to-play fluff on the App Store. Definitely an empowering move that will hopefully give us exceptional and well-made games made exclusively for mobile. Definitely an A+ selection of content creators, which are more than capable of bringing the next Monument Valley to your iPhone and iPad.
