Mario’s nipples are not for all ages
Super Mario Odyssey will be the first mainline Mario game to receive a CERO B rating in Japan.
CERO is Japan’s video game classification board. Much like ESRB in the United States, CERO is used to help parents decide what games are appropriate for their children.
Up until now, every core entry in the Mario series has been given a rating of CERO A (suitable for all ages.) Super Mario Odyssey is breaking the streak with a CERO B rating (suitable for 12 years and above.)
It remains to be seen what prompted the new rating, but I’d wager it has something to do with Peach’s forced marriage to Bowser and Mario’s exposed nipples.
