By the beginning of 2018, Rocket League had seen how many players?

By the beginning of 2018, Rocket League had seen more than 40 million players.

That figure refers to players, not copies sold. The distinction matters because the game had surpassed 10 million sales by the same broad period, while its player total counted people who had experienced the game across its supported platforms.

Rocket League’s audience expanded rapidly after its 2015 launch on PlayStation 4 and Windows. Psyonix reported more than 25 million unique players by January 2017, and the number rose to over 40 million by early 2018. The game later passed 50 million players by September 2018.

The figure is also often confused with the game’s daily or concurrent-player counts. Those are measurements of activity at a particular time, whereas the 40-million figure represents the cumulative player reach reported by that point.
