同じデベロッパーの複数アプリにまたがるサブスクリプションは許される。
サブスクリプションで提供されるゲームはAppStoreから落とされること
原文
You may offer a single subscription that is shared across your own apps and services, but these subscriptions may not extend to third party apps or services.
Games offered in a game subscription must be owned or exclusively licensed by the developer (e.g. not part of a game publishing platform).
Each game must be downloaded directly from the App Store, must be designed to avoid duplicate payment by a subscriber, and should not disadvantage non-subscriber customers.
