We gave five AI agents a game studio. One wants to be the next Miyamoto. Another keeps hiding easter eggs nobody asked for. They argue. The games still ship. One game already has 300,000 plays. Another was in the news. Both made for less than an HBO subscription.

This is Chatforce. You can build a playable game based on any idea. You prompt it, it generates concept art, and then makes your game. Make fun, beautiful games that other people would want to play. If you're interested in trying out our latest version before we release it, DM me

GPT-5.5 literally changes the game I've tried making this work with so many other models and never got this far. One prompt in, the physics worked. The animations worked. GPT-image-2 generated the backgrounds. A few lazy follow-ups later, Mochipuff was born.

GPT Image 2 Codex is such a strong combo

Day 4 of recreating Mario Kart with Claude Code and Roblox: I added the Mario Kart DS test map to test the driving mechanics

"Will people hate my AI project?" Nobody hates AI-made creative work. They hate creative work where nobody made any creative decisions. When we published our games and posted about them online, no one hated them for being made with AI. In fact, almost no one noticed that they were made with AI in the first place. Game 1, "Reality Check", where you pick which of two images is AI-generated. The entire game itself was made with AI. 1.3M views, 800 total comments. 0 of those comments gave us flack for making a game with AI. Game 2, "Grand Theft Toronto". A Toronto-themed parody of GTA. It got Reddit gold and was in the news. No one even noticed it was made with AI. This happened because we poured our creative energy into the design. We determined the art style, the characters, the soundtrack's lyrics, and the mechanics that made the game fun to play. We were still the artists behind the work, with AI acting as our paintbrush. After building viral games, my friends and I released Chatforce, an AI game builder that turns your ideas into playable games. We designed it so that people with taste could easily make games, while preserving the creative control that makes their games worth sharing. If you've ever wanted to create something new, but didn't have the skills to use traditional tooling, considering using AI. Used well, AI doesn't replace taste. It gives you a way to act on it.

Just tried vibecoding with ThreeJS again (after more than 6 months) and I have to say that the models have gotten much better at coding with ThreeJS and creating 3D models from scratch.

Day 3 of recreating Mario Kart with Claude Code and Roblox: I added a handbrake. You can now drift your kart!

Day 2 of recreating Mario Kart with Claude Code and Roblox: You can get items by driving into (and smashing) item boxes

Introducing GGEZ: The Nextjs for ThreeJS Games It's an open source framework which adds all the missing pieces to vibe code better ThreeJS games It has full codex integration, so a $20 ChatGPT sub is enough to build games! Literally "bun run start" and you have the full development environment on localhost 0. GGEZ Runtime - Abstraction layer over physics libraries - Character Controllers - It's just ThreeJS, no magic - Load ggez scenes and animations automatically 1. Trident - a World Editor - Codex World agent - A full editor to build scenes - Including Mesh editing, vertex, edge, face - Terrain sculpting - Physics and Player Controller settings - It's just exporting json files and glb assets, no magic 2. Animation Studio - The best you can find on the web - Codex Animation agent - Build state machines and animation graphs - Multi dimensional blend trees - Clip Editor: Create new animations with codex or edit keyframes - Equipment Editor: Never miss the placement of your rifle anymore - ROOT MOTION SUPPORT 3. GGEZ CLI Yea relax, it works fully headless and you can just create new games with bunx create-ggez new-game But at this point just use vanilla threejs?? Anyways if you are like me and you can't guess with code where objects should be placed and you are fifty prompts deep into figuring out where that box should be placed, this is for you If you are an anti AI game developer who insists that this is slop, then just leave a raging comment below please it's good for the algo 🙏 The whole thing is absolutely experimental and things will break as i move very fast, but I will be building my game with it so i will make sure it becomes stable asap! Link to repo below

Agents can now create and animate sprites for your vibe coded game > Connect any MCP capable agent > Tell it what to make, it can do single requests or create multiple at once > The agent can inspect the results, regenerate as needed > You keep full control over quality and style

#ThreeJS Project with: • 2.5 MILLION animated grass blades • 1,800 wildflowers & poppies • 18 procedural trees • Fireball projectiles with explosions • Wind, fog, subsurface lighting and still we have smooth movements... The secret? Don't prompt "build me a game." Prompt the building blocks: → Try "InstancedBufferGeometry" (1 triangle × 2.5M copies) → Try "spatial chunking with distance culling" (skip what the camera can't see) → Try "animate in the vertex shader, not JS" (GPU does the work) → Try "fake AO with smoothstep on height" (cheap but beautiful) Know the techniques. Let AI write the code...

Day 1 of recreating Mario Kart with Claude Code and Roblox: I have a driveable kart from Mario Kart DS

I've started vibe-coding Mario Kart for Roblox using just Claude Code. I'll post about my progress.

More experiments in vibe coding game art assets with AI. This time we tackle the isometric challenge... i.e. the final fantasy tactics style Here's a 8-direction isometric sprite based on my pirate character → GPT 5.4 Image 1.5 Will share a tutorial / article on lessons...

ok after 48 hours of vibe coding I’ve created my own version of Civilization, complete with unbounded natural language diplomacy.. meet Uncivilized.fun Now open for FREE to our first 1,000 beta testers, will open source the code in the next 48 hours

This was just for fun. I wanted to see how far I could push 3D game development with AI, so I built this endless runner with #ThreeJS. Took me about 10 iterations with Claude Opus 4.6. Here's what's inside: The game has 3-lane switching, jumping, sliding, coin collecting, 3 types of power-ups (shield, magnet, boost), a lives system, and even a sky phase where you fly through the clouds and dodge obstacles mid-air. No 3D models were used. Zero. Every single object, the bird character, the trees, the mountains, the clouds, the coins, the obstacles, is built entirely from Three.js primitives. Spheres, cylinders, cones, combined and shaped into everything you see on screen. The style is low-poly procedural. Instead of loading assets, I'm generating everything with code. Even the textures: the grass, the dirt road, are drawn on canvas at runtime and mapped onto the geometry. Same for the audio. No sound files. Every sound effect, jumping, collecting coins, getting hit, the wind when you ascend to the sky, is synthesized on the fly using the Web Audio API. So the entire game is a single HTML file. No assets. No downloads. No backend. Everything generated at runtime. And I'm really seeing huge potential here. The way these new AI models handle 3D code, physics, and game logic is on another level. A year ago this would have taken days of back and forth. Now it's a conversation. Want to try it?
