Which Mario Kart 8 Deluxe DLC served as a stopgap while Mario Kart World’s development continued?

The Booster Course Pass for Mario Kart 8 Deluxe served as a stopgap while Mario Kart World’s development was prolonged. It supplied new content for the existing game during the long wait for the next major entry.

Mario Kart World began development in 2017, but its expanded open-world ambitions and the eventual transition to Nintendo Switch 2 made the project a lengthy one. Nintendo continued supporting Mario Kart 8 Deluxe with additional courses during that period.

The Booster Course Pass was released in waves and added returning tracks from earlier Mario Kart games. It was not Mario Kart World downloadable content; it was an expansion for Mario Kart 8 Deluxe. That distinction is a common source of confusion because both projects involved remastered and reimagined courses from the series’ history.
