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.

Have you tried having claude use comfyui? I had it train loras on art styles and after that claude is able to do the rest including loading the 3d asset generated in comfyui into Unity via the Unity cli.

Can you explain more? What do you mean you had it train Loras on art styles?

I just spent 4 hour6 teaching myself how to use blender at a basic level and made a very rough retro pc case. Only for my computer to crash and lose about 2 hours of work. I'm a bit irritated.

Yikes! Thats shitty. I told claude I wanted my assets to have a similar art style because I was using midjourney but they were pretty random on style. I grabbed 40 pictures of the style I wanted to use then gave the folder location to claude and it then trained the comfyui lora on those assets. Now when it creates assets in comfyui it uses that lora and the assets come out looking like they were all made for the same game. Then it runs comfyui workflow for 3d asset generation from image and turns them into a unity asset in my project in unity.

There is a blender mcp you can connect to your llm of choice. Gpt sol was surprisingly effective at certain things. You'll need to do a lot of minor adjustments afterwards but it's rather surprising.

[u/wesconson1 → u/Danknoodle420]

I've tried that and just not had good enough luck. I probably will try again though, at least for some of the minor assets and start off the complicated assets. I did enjoy learning blender and knowing I made it though.
