Two months ago, we started a wild experiment:
What if a player could just type a sentence — and an AI would generate a playable game world from it?
No big team. No custom artwork. No traditional game dev pipelines.
Just a couple of creators, some clever prompts, GPT, and image generation APIs.
Surprisingly, it worked.
Our AI game, GameAI World, attracted over 10,000 players in 60 days — and turned profitable in the very first week.
Here’s how it happened ????
Inspired by "Unbuildable" Game Design Docs
All of us come from game development backgrounds, and we’ve written plenty of design docs that never saw the light of day.
One day we joked: “Why not let AI actually build the games we never could?”
Story generation? ✅
Art creation? ✅
Dialogue choices? ✅
Mini-games? Why not.
The more we joked, the more serious it became.
That’s how GameAI World was born.
The pitch:
“Type a prompt. Let AI generate an entire mini-game universe.”
MVP in 3 Days: Fast, Dirty, and Playable
We built the first prototype in 72 hours.
-
Frontend: plain HTML/JS + OpenAI + Stable Diffusion API
-
Users input a story idea (e.g. “I’m an astronaut building a base on Mars”)
-
The system generates:
-
Background artwork
-
Character portraits
-
Opening narrative
-
Three interactive choices
-
A small task/mission (e.g. resource gathering)
-
Everything is AI-generated in real-time.
All we built was the “stage.”
We posted it on Reddit and Twitter.
Day one: 1,000+ unique users. Totally organic.
Monetization: Let Players “Sponsor” Their AI Characters
The first version was free — until our API bill exploded.
We didn’t want a full-blown subscription system, so we tried something playful:
For $5, players could create a unique AI character — with a custom portrait, backstory, and shareable link.
The idea worked.
300+ people paid in the first week. Some even made entire AI character collections.
Even better: these characters went viral.
People shared them on Twitter, Discord, and even Instagram — giving us 5x exposure overnight.
It’s Not the Tech — It’s the Experience
We’ve been asked: “What advanced AI stack are you using?”
Truth is, it’s simple:https://snakegame.run/ https://rednoteapp.io/ https://mergefellas.info/ https://slogangenerator.ai/ https://veo3.im/
-
GPT-4 for dialogue and plot
-
Stable Diffusion for art
-
A prompt manager with some guardrails
What took time was:
-
Keeping generation under 10 seconds
-
Guiding users to write effective prompts (with templates)
-
Filtering and retrying failed generations
In other words: we didn’t obsess over the models — we obsessed over the UX.
Some Painful Lessons
-
Free users burned through our API budget fast
→ Added generation limits + fun “your adventure is loading” screens -
Image quality was inconsistent
→ Added style prompt templates + image quality filters -
People typed garbage inputs
→ Added example templates like:
“I want to be a [hero] in a [setting] who must [goal]”
What’s Next?
We’re building:
-
Multiplayer storytelling: Let players co-create and act out stories together
-
Mobile version: Launching on WeChat mini program and PWA
-
Character growth: Characters that evolve over time (maybe even tradeable)
-
Subscription perks: Premium templates, image styles, priority generation
What We’ve Learned
✅ You don’t need to “build everything” — just nail one addictive experience
✅ AI isn’t the magic — gameplay design still matters most
✅ Sharing is marketing — give players a reason to post their creations
✅ Prompt scaffolding boosts retention
✅ Don’t ship more features — polish the one that keeps people playing
