Sweeney argued that his intention was to trigger a general change in smartphone industry practices, rather than pursue a special exception for Epic Games and Fortnite. However, Fortnite's declining performance on iOS suggests that Epic may well need Google Play support to recapture growth.
As with other battle royale titles, Fortnite has seen a general decay across PC and console platforms since its mid-2018 peak. However, whilst PUBG Corporation's PUBG IP has flourished in its transition to smartphone via Tencent, Epic's title is flatlining. According to Priori Data, in Q3 2019, Fortnite saw a decline of -65% year-over-year in net revenue on iOS. It now generates just over a third of the revenue it did at peak, and Q4 looks to remain flat, with marginal recovery from the Star Wars event.
As App Store users are monetized far more effectively than those on Google Play, and due to a lack of easy access, it is likely that Fortnite is generating less than half its total mobile revenue on Android.
If Fortnite were to launch on Google Play, it would likely see a surge of interest in emerging markets such as India due to greater exposure and accessibility. IHS Markit Technology data shows that 95% of smartphone devices in India are Android, and high-growth territories across South America and Southeast Asia are also Android-first. These markets have already been tapped by competing publishers and titles, such as PUBG Mobile and Garena's Free Fire, which are highly visible on Google's app store: PUBG Mobile now even has a lite version.
It seems unlikely that Google will be willing to revise its 70/30 revenue share model in the near future, especially as it gives developers the option of distribution via their own channels – something which is currently not even permitted by Apple on iOS. As such, Epic will have to decide if the exposure and potential new growth afforded by the Play Store is worth surrendering 30 percent of its Fortnite revenue.
