When Fortnite Battle Royale launched on Android, it made an unusual choice: it bypassed Google Play in favor of offering the game directly from Epic Games’ own website. Most apps and games don’t have the luxury of making this choice – the built-in distribution Google Play offers is critical to their business. But Epic Games believes its game is popular enough and has a strong enough draw to bring players to its website for the Android download instead. In the process, it’s costing Google around $50 million this year in platform fees, according to a new report.

As of its Android launch date, Fortnite had grossed over $180 million on iOS devices, where it had been exclusively available since launching as an invite-only beta on March 15th, before later expanding to all App Store customers.
