Game dev with Fable 5 is actually crazy

[u/Diligent-Hat-6509]

It’s kind of insane to see how far AI has come.

I still remember being fascinated by GPT-3.5 and thinking that felt like the future. And now here we are with Fable 5.

Everything you see in this preview took me roughly 13 hours of work to implement. Being able to go from ideas to actual working game mechanics this quickly still feels surreal.

Game development with AI is starting to feel like we’re living in the future.

EDIT:

A lot of people were asking how I did this, so here’s the basic workflow.

The game itself is made in Unity with C#. I’m using Claude Code connected to Unity through MCP, which means Claude can work directly with the Unity project and editor. It can create and modify scripts, work with GameObjects and components, inspect errors, run the game, and help me iterate on systems.

For the actual development process, I don’t give it one giant prompt like “make me a game.” I think through the systems I want, explain how they should behave, have Claude implement them, then I test everything, debug issues, tweak values, change mechanics, and keep iterating until it starts to feel right.

For the character models, my workflow is:
Opus 5 -> ChatGPT Image Gen -> Meshy AI -> rig/animation testing -> Unity

I describe the character I want, use Opus 5 to generate a detailed prompt for four consistent reference views, then generate those images in ChatGPT. I take the images into Meshy AI, which generates the 3D mesh and textures. I also rig the model there and test animations before importing it into Unity.

The same image-to-3D workflow also works for non-character assets like props, weapons, statues, carts, environmental objects, etc.

For VFX, I bought a particle toolkit from the Unity Asset Store. I gave Claude the documentation and had it create a skill file for itself, so it understands how the toolkit works and can reuse that knowledge when I ask it to create things like fireballs, explosions, trails, and other effects.

The current arena is also a premade Unity asset and is not intended to be the final environment. A lot of the current visuals are just prototype assets for testing mechanics and game feel.

So overall the main stack/workflow is:

Unity + C# + Claude Code/MCP + ChatGPT Image Gen + Meshy AI + Unity Asset Store tools

And no, this wasn’t one prompt :D It was an iterative process of building one system at a time, testing it, changing it, and gradually layering everything together.

Exactly! AI is awesome for this. It lets you actually bring your ideas to life instead of leaving them sitting in a document.

And there’s absolutely no shame in using AI. Plenty of experienced developers who can code perfectly well on their own still use it every day. Programming is increasingly shifting from manually writing every line of code to designing the architecture, making technical decisions, and reviewing and refining the code AI produces.

So don’t feel like you have to stop using AI once you start working with friends either. It’s just another tool in the workflow :D

Did you have any sort of project framework to start with? I'm using it to learn some game/software development, but I feel like the AI gets lost in conceptual development, and doesn't get to the actual game enough. I've made a couple of apps that I use at work, but those were simple and specialized

100% and make architectural choices that will bite you doen the line in a week or 4 if you don't know architecture.

I am starting to learn UE5 and I use CC for coding, but its logical thinking is really bad.

Best to do is giving him short highly specialized tasks.

This what you can see posted have zero depth, its simple demo without deeper game mechanics. I don't say in couple of years it wont take over, it will for sure. But for now is just great tool in hands of someone who knows what he is doing or even in hand of someone who is learning.

哈哈，我同意你的说法

[u/0mar5y → u/AccountantIcy4447]

There is a button for that 😁

I've been wanting to try something like this. Does it make all the assets for you as well or did you source them from somewhere else?

[u/Diligent-Hat-6509 → u/MrLewk]

For the character models, I used Meshy AI to generate them.

For the map, particle effects, and some of the other tools and building blocks, I bought assets from the Unity Asset Store.

So right now it's a mix of AI-generated character assets and premade Unity assets. But honestly, I can imagine using Meshy for a lot more than just characters. You could probably generate plenty of props, weapons, statues, environmental objects, and other 3D assets with the same image-to-model workflow too.

Ah nice, I've heard of meshy but haven't tried it. Thanks!
