Google is expected to miss out cashing in on the Fortnite craze due to Epic Games' decision to distribute the Fortnite Mobile APK outside the Play Store. App Store intelligence firm Sensor Tower projects that Google might stand to miss out on more than US$50 million in platform fees for the remaining part of 2018. Circumventing the Play Store might have a slight impact in overall downloads of the game but its revenue potential stands to remain fairly unaffected.
