Super Mario Fans Attempt World Record in Union Square, Novel York City

New York City’s Union Square was transformed into a vibrant, real-life “Mario Party” on Tuesday, March 10, 2026, as fans dressed as various iterations of Nintendo’s iconic Super Mario character gathered in an attempt to break a Guinness World Record. The event, held on “MAR10” Day – a nod to the “Mario” name and the date March 10th – was organized by GameStop.

GameStop Incentivizes Participation

GameStop offered a $5 store credit to anyone participating in the event while dressed in a Mario costume, drawing a large crowd of cosplayers representing the character from across different eras of the video game franchise. The company is aiming to surpass China’s existing record for the most people dressed as Mario in one location.

The Significance of “MAR10” Day

March 10th has become a popular day for fans to celebrate the Super Mario franchise, with events, promotions, and tributes occurring worldwide. The day’s significance stems from the visual similarity between “MAR10” and “Mario.”

A Nostalgic Appeal

According to Nicolle Robles, GameStop’s Director of Communications, the enduring popularity of Mario is rooted in nostalgia and the character’s association with carefree childhood memories. “He’s a reminder of people’s childhoods and a carefree time, and you know people still play video games well into adulthood,” Robles stated.

Nintendo Switch 2 Announcement

The event took place not long after an announcement for the Nintendo Switch 2 was displayed at a GameStop store in Union Square on April 4, 2025 [1], signaling continued interest in the Nintendo franchise.
