The launch of Fortnite Battle Royale has left Google in a slight predicament. While Google is in no way hard up for cash, Fortnite Battle Royale for Android certainly represented the potential for a relatively big revenue stream for an app. That is, until Epic Games decided it would launch Fortnite for Android from its own website, circumventing the Play Store.

But revenue aside, there’s also the matter of Google probably not liking the idea of huge titles circumventing the Play Store as a precedent. Plus, the lack of Fortnite Battle Royale within the Play Store poses a slight security risk to users, as there are quite a few V-bucks scams and malicious clones looking to capitalize on the popularity of Fortnite.
