Video games offer a melting pot of intellectual property: trademark law, copyright law, and even patent law all come together in a delicious mix of intangible property. However, not all video game franchises are equal. Few can claim the same level of longevity, success, and nostalgia as Nintendo’s Mario Brothers series.

Among the most popular titles of the franchise is Mario Kart, a game in which characters from the franchise race each other in go karts. The characters repeat catch phrases, seek out power ups (invincibility, speed, etc.) and cartoonish weapons (banana peels, turtle shells, etc.), all with the singular goal of being atop the podium at the end of race. Over its 25+ years of existence, the game has resulted in significant sales, widespread nostalgia, and, unsurprisingly, numerous attempts from others trying to make money off of the characters. But a recent lawsuit in Japan brought media exposure to what might have been the greatest attempt yet to profit off the franchise: real life go-karting in Mario Brothers costumes in the streets of Tokyo.

How fun is that? From what I can tell, riders aren’t allowed to throw things at each other (thanks a lot, safety laws), but this tour would still be great. The attraction even attracted professional race car drivers. You don’t even need to provide your own costume, they’ve got a ton for you to choose from.

Race car drivers weren’t the only people to discover the tour. Nintendo’s lawyers did, too. I’d like to imagine they participated at least once before suing them, if only under the pretense of “fact development.” Nintendo sued and ultimately prevailed on claims of copyright infringement. The company has to pay Nintendo 10 million yen (about US$89,000) and can no longer hand out Mario Brothers character costumes.

It’s hard to quibble with Nintendo’s actions here. The MariCar company intentionally distributed character costumes in order to attract customers.

But what are Mario Kart fans supposed to do now? Well, there will be an official Super Nintendo World opening at Universal Studios Japan ahead of the 2020 Tokyo Olympics. The theme park will include a Super Mario World featuring Bowser’s castle, Peach’s Castle, and, yes, a “Mario Kart attraction.”

But if you prefer the thrill of participating in likely infringing activities, you can check out the Australia-based MUSHROOM RALLY race event purportedly coming to Denver, soon. Participants will have a chance to battle it out in Las Vegas for the championship race. Ticket prices are yet to be determined and are limited to just 600 participants. I suggest you read the fine print on the refund policy though – just a hunch…
