More than 12 million players logged in for Fortnite's concert featuring Travis Scott, with reviewers calling it "stunning" and "spectacular".
It included a skyscraper-sized version of Scott teleporting across the landscape as he performed his songs.
Fortnite is one the world's most popular games, attracting millions of young players from across the globe.
Scott used the opportunity to reveal a new song, while players celebrated the event with themed in-game items.
The award-winning artist has sold tens of millions of records in his career, and was due to perform at the world-famous Coachella music festival this summer before it was postponed.
Those who missed the digital debut, however, can catch "encore" performances at the weekend.
A digital version of Scott performed a fully-animated, scripted 10-minute set - shorter than a concert performance.
As Scott moved from song to song, his virtual avatar changed - first into a cyborg, then a fluorescent spaceman.
