Nintendo Denies AI Claims for Mario Kart World Trailer

|
- Nintendo was criticized for alleged use of AI in the Mario Kart World trailer.
- In an exclusive interview with Eurogamer, Nintendo denied the allegations.
- Viewers believe AI was used for the in-game billboards, which appear disproportionate in nature.
After noticing misshapen objects within in-game billboards, viewers criticized Nintendo for alleged use of AI; Nintendo denied these allegations in an exclusive response to Eurogamer, who reached out to Nintendo for an answer.
“AI-generated images were not used in the development of Mario Kart World,” a Nintendo spokesperson said, rejecting the notion that AI was used. The billboards in question are showcased below.

One of the billboards showcases a misshapen car with windows that are almost top-hat-like in nature—the car appears as if it was cartoonishly stretched out. Another billboard has an in-progress skyscraper with “WE BUILD YOUR DREAMS” spelled out next to it. The buildings lack proper architectural physics; the windows and floors are strangely positioned. Both billboards’ lack of proper representation of real-life objects sparked the AI allegations.
Mario Kart World’s release date is on June 5, 2025, the same day the Nintendo Switch 2 debuts because the game is included as a part of a Nintendo Switch 2 bundle. The last mainline Mario Kart game was Mario Kart 8 Deluxe. The original iteration of Mario Kart 8 came out May 29, 2014, more than 10 years ago.
