Google has just dropped something that truly represents the first real step toward user-created gaming. Known as Genie 3 (G3) and developed by Google DeepMind, it is an evolution of generative AI that I have been eagerly awaiting.
The first game to ever truly capture my imagination and immerse me in the world it created was Fallout 3. I recall being stunned by the detail of the game, the potential it afforded me to be good, bad, or just simply feral (I went with feral). Somehow this game captured memories from my childhood of playing with my friends, where the only limits were the ideas we could come up with.
Age tends to fade our imagination unless we work to keep it strong and for me, games have always been a way of keeping it alive. When Fallout 4 dropped, I spent hours making my wasteland home an impregnable fortress, with gun turrets arranged in interlocking fields of fire, and barricades that funnelled enemies into the killing fields. That aspect of the game alone ate many hours of my free time, way before I even got around to the missions and the actual plot. Looking back, I can see now that it was the fact that I could craft my own little world within that game that hooked me so successfully.
Genie 3 now looks set to turn gaming into something completely new, and it opens the door for users to craft their very own Matrix.
The Technology
Genie 3 is not like a traditional video game with its rigid physics and deterministic code. No, with G3 the model functions as an autoregressive dynamics model, in plain English, that means it predicts the next frame based on the user’s action.
Google trained this 11-billion-parameter model on 200,000 hours of internet video, and it essentially taught itself the rules of 3D space and movement. In terms of user input, this model works with a standard controller, like WASD or a gamepad, and the system generates the world’s response on the fly.
However, the aspect that really caught my attention was how these worlds are birthed. Through a process called “World Sketching,” users can upload a hand-drawn sketch or a photograph from a fond moment in the past, and G3 uses it as a blueprint for the world it then crafts.
There are limitations, as the technology is still in early stages:
- Resolution: Capped at 720p.
- Frame Rate: Runs at 24fps, which provides a cinematic flow but is the minimum for smooth play.
- Access: Currently restricted to high-end cloud infrastructure via a Google AI Ultra subscription, costing up to $250 a month.
- Session Length: Capped at 60 seconds to manage immense compute costs and prevent “context window drift,” where the AI starts to “forget” the world.
Copycat Games
G3 is already so good at creating worlds from prompts that it can replicate protected IP from major franchises. In theory, G3 could whip you up a version of Super Mario 64 or Zelda using accurate models for the characters, mechanics and all. Google has already been forced to implement reactive guardrails to blacklist certain keywords to appease third-party providers.
Here is the thing: there was a time (not long ago) where LLMs were only available via expensive subscriptions. Now, that same tech can be run from a local machine with all limitations switched off. In a few years, users will likely be able to create their own versions of games with personal tweaks to level design, character models (Lara Croft should be worried), or even create crossovers from different titles.
This disruption has already rattled investors, with share prices for Unity (-21.6%) and Roblox (-12.3%) diving upon the announcement. While some, like Unity’s CEO, believe this tech will eventually be integrated into existing engines to enhance them, 52% of industry professionals fear it is harming the sector, with some critics dismissively calling it “Slop Simulator 2026.”
The Future is Bright
One of the major problems with AI, for me, was how it is removing the need for humans to think for themselves. Our minds stand to atrophy in the areas that do not get worked out enough. What G3 represents is an AI tool that actively encourages the imagination to fire up and explore its own depths once again.
In a few years, we might well be able to generate an explorable world from photographs of our past. This opens up massive potential for therapeutic use, especially for those who wish to revisit places in time they cannot or will not visit in the physical world. Think of PTSD sufferers who are mentally trapped in the location of a trauma. The ability to safely explore and interact with a generative world, stabilised by the model’s “emergent memory”, could be incredibly powerful.
G3 is the first time I have seen more positive possibilities on the horizon than bad from AI. I am truly excited to once again have the opportunity to flex my imagination’s muscles. Others may use it to visit their childhood street from decades ago and relive the emotional markers left behind. No matter what it is used for, one thing is clear:
Not far from now, we could well be living in a world where your mind is the only limit, and that is exciting as hell.
