Five years after Mario Kart 8 Deluxe hit store shelves, Nintendo has finally begun churning out DLC tracks through the Booster Course Pack, and it has shown that Mario Kart 9 may not be needed for a little while. Fans of the series have been calling for a brand-new Mario Kart, as Mario Kart 8 Deluxe is only an upgraded version of a game that came out in 2014, but the DLC seems to have given the game a fresh coat of paint. It almost feels like a new game now, and has offered boatloads of content for Mario Kart fans to enjoy for years to come.
