How many copies of Rocket League had sold by April 2016?

By April 2016, Rocket League had sold about 4 million copies.

Psyonix reported in February 2016 that the game had sold at least four million copies and generated roughly $70 million in revenue. That figure referred to paid copies and excluded PlayStation downloads distributed through promotions such as PlayStation Plus, so it was not the same as the game’s much larger player or download count.

That distinction mattered because Rocket League had reached millions of additional players through free promotional access. Psyonix tracked at least 12 million unique players at the time, including people who had downloaded the game without purchasing it. Sales, downloads and unique players therefore measured different things.

The commercial momentum continued rapidly. By July 2016, Psyonix reported more than 6.2 million sales across platforms. By March 2017, the total had passed 10.5 million copies, and the game had 29 million registered players. The April 2016 milestone belongs to the earlier four-million-sales stage of Rocket League’s breakout success.
