Update: While Epic did not offer API data access until the last few years, they tweeted in 2021 that the Galactus event had 15.3 million players, which would put it above this one. Original article follows:
If you think Fortnite peaked years ago, you’re just wrong, no two ways about it. The game continues to grow and grow and now, it has set a new concurrent playercount record with several million more players than the previous one for the Big Bang event.
Fortnite just put on a sprawling virtual concert starring Snoop Dogg, Eminem, Ice Spice and the deceased Juice WRLD, with the show meant as a tribute to the late rapper. Lasting about 15 minutes or so, each performed a song or two, ending with Juice WRLD getting the stage to himself as players floated around in crystal butterfly form.
It’s the third concert event of this scale with the Travis Scott and Ariana Grande shows before this. Fortnite has featured a lot of music and musicians over the years, but most are now integrated into Fortnite Festival rather than a large-scale event like this. Lady Gaga and Billie Eilish, for instance, have music and skins in the game, but they have not had huge showcases like this.
