You’ve seen the viral posts: “I made Minecraft with one prompt using Gemini 2.5”
Sounds too good to be true, right? In our latest stream, we actually put that claim to the test using Rosebud AI Game Maker.
We tried to recreate some of the internet’s most jaw-dropping examples using Google Gemini 2.5 Pro—and let’s just say, reality hit a little differently. But the results? Still pretty mind-blowing.
From Minecraft clones to flight simulators and 3D racing games, Google’s latest multimodal AI model showed real potential as a tool for AI-powered game development.
But there’s a catch—and that’s where platforms like Rosebud come in.
Watch our recent livestream where we put it to test:
What Games We Vibecoded with Gemini
During our stream, we challenged Gemini 2.5 Pro to build actual playable games—and it delivered.
We created a Dune-style Minecraft clone with block placement, terrain generation, and even walking NPCs.
We also managed to build a 3D car simulator complete with a train circling the track, textured ground, and basic lighting effects.
And we even made a flight simulator where you can zoom through a dynamic world with third-person camera controls.
Not bad for a few prompts (and a lot of trial and error). Seeing these projects go from prompt to playable in real-time was a perfect showcase of Gemini’s coding chops—especially when paired with Rosebud.
Gemini 2.5 for Game Dev: What Worked (and What Didn’t)
Here’s what we learned:
• Gemini is powerful, but finicky. You need to be very specific with prompts. Even small changes in wording can break the code or cause black screens.
• Single-file projects work best. Multi-file projects tend to confuse the model unless you really spell things out. That’s why using a game development platform with clear templates (like Rosebud!) makes a huge difference.
• Recreating viral games is hard. While we managed to build impressive demos, they took multiple iterations. The “one-prompt magic” isn’t quite there yet.
• But wow, some results are beautiful. Gemini was able to generate full textured environments, skyboxes, moving vehicles, and even basic NPCs with believable behaviors.
Why Use Rosebud with Gemini 2.5?
If you’re planning to experiment with Gemini 2.5, we highly recommend trying it inside the Rosebud AI Game Maker. It gives you:
✅ Ready-to-use templates for single or multi-file setups
✅ Instant previews of the game without downloading anything
✅ Rosie, our AI assistant, who fixes broken code so you don’t have to
✅ The ability to remix and iterate quickly without losing your progress
It’s like having your own AI-powered dev environment, optimized for creative chaos.
Final Verdict
We've tried GPT-4.5, Claude 3.5, and even DeepSeek, and none of them delivered working 3D games with as much style and consistency as Gemini 2.5.
That said, if you’re serious about game creation, it’s not just about the model—it’s about the platform you use to bring it to life.
