Google just dropped Project Genie on January 29, and the gaming world is already buzzing ,mostly because this AI tool can churn out interactive worlds that look suspiciously like your favorite Nintendo games.
The experimental prototype, available exclusively to Google AI Ultra subscribers in the U.S., lets users create playable 3D environments from nothing more than text prompts or uploaded images, and early tests show it’s capable of generating remarkably convincing knockoffs of Mario, Zelda, and Metroid.

How Project Genie actually works
Built on Google DeepMind’s Genie 3 world model and powered by additional AI systems including Nano Banana Pro and Gemini, Project Genie operates through three core features: world sketching, exploration, and remixing.
Users can describe a character and environment through text prompts, choose a camera perspective, first-person, third-person, or isometric, and define how they’ll navigate the world, whether walking, flying, driving, or swimming.
The system then generates an interactive environment in real time, predicting and rendering the path ahead as users move through it at 20-24 frames per second in 720p resolution.
The Verge’s Jay Peters tested the tool firsthand and successfully generated worlds inspired by The Legend of Zelda: Breath of the Wild, complete with a paraglider-equipped Link exploring green fields and mountains.

Other users quickly created environments resembling Super Mario 64, Metroid Prime 4: Beyond, and even Grand Theft Auto-style cityscapes. However, the prototype comes with significant limitations: generated worlds are capped at 60 seconds, character controls can be laggy and unresponsive, and the visuals don’t always match prompts or adhere to real-world physics.
Google acknowledges worlds “might not look completely true-to-life”, and some features previewed in August 2025, like promptable events that dynamically change the environment—aren’t included yet.
Nintendo’s lawyers are probably already warming up
Here’s where things get legally murky. When Peters questioned Google about using copyrighted characters, the company blocked Mario-based prompts mid-testing, displaying a message citing “interests of third-party content providers”. Yet Zelda and other Nintendo properties remained accessible, at least temporarily.
Google product manager Diego Rivas offered a vague response, stating the prototype is “designed to follow prompts a user provides” and that the company is “monitoring closely and listening to user feedback”.

The tool was trained “primarily with data available publicly on the web”, Rivas added, though that doesn’t sidestep copyright law. Nintendo has historically taken aggressive legal action against anything resembling infringement.
The company shut down fan projects, issued DMCA takedowns on emulators like Yuzu (settling for $2.4 million in 2024), and even sent legal demands to charitable speedrunning events using Nintendo games.
In 2025, Nintendo promised to take “necessary action” over AI copyright violations after Sora-generated spoofs went viral. Given that Project Genie can instantly produce interactive Nintendo-like environments available to anyone with $249.99 per month to spare on Google AI Ultra, it’s hard to imagine Nintendo’s legal team staying quiet for long.
The launch already spooked the gaming industry, stocks for Unity Software dropped 12 percent, Roblox fell 8 percent, and Take-Two Interactive declined 7 percent on January 30 as investors worried about AI’s potential to disrupt game development.
Whether Google has the muscle to withstand a potential Nintendo lawsuit remains to be seen, but one machine learning ops employee quoted in a recent Game Developers Conference study put it bluntly: “We are intentionally working on a platform that will put all game devs out of work“.
