In a recent interview, Kosuke Yabuki, the producer of Mario Kart World, revealed the reasoning behind the game’s exclusive focus on the Super Mario universe. Unlike previous entries that featured crossover characters from other Nintendo franchises, Yabuki stated that the development team felt it would be incongruous to introduce non-Mario characters into a game that is fundamentally about the Mario-themed world. This decision emphasizes the game’s commitment to its roots, allowing players to immerse themselves fully in the beloved universe.
