Rather than something like what you get from Microsoft, Sony or Google's new cloud-based game streaming service, Apple will instead include an offering of premium paid games from various developers. These games will be exclusive to Apple and will have a dedicated tab in the App Store. Apple will charge people a monthly fee for the service, but it didn't say how much yet. 

Apple Arcade will be available for the iPhone, iPad, Mac and Apple TV this coming fall in more than 150 countries worldwide. With the subscription, Apple said people can play as much as they like without ads or additional purchases. They'll also be able to play offline.
