I made a Dark Souls-inspired Three.js game with Sol Ultra using Codex Sites. It's fully playable in the browser. I handled the prompts, references, and libraries like img2threejs. The game has shield blocking, dodge rolls, archery, and a full inventory system. Still blows my mind that you can build... show more

Another WTF moment. Using Codex as a fully custom game engine With the newly discovered and *insane* img2threejs skill 1) GPT imageGen a 3D item you want 2) ask GPT 5.6 Sol to use img2threejs 3) my harness brings it into the game automatically Just watch how good this is

I tested my Blender character creation skill with Codex + GPT-5.6 Sol Ultra. The full prompt: “Create a Three.js game where the player explores different biomes. Create the character and animations with skill-blender-character.” Codex built the world, created the low-poly character in Blender, generated the outfit and integrated the animations into the game. One prompt, one custom skill, one playable prototype.

So this game is real now, fully built with GPT-5.5. I told Codex to use the imagegen skill to generate a reference UI and sprites, and used the Build macOS Apps plugin to build the app for a native retro fantasy labyrinth game! Adjusted the UI in a few prompts and here we are!

Codex is unusable. I generated one image with GPT Image 2.0, gave it to Codex, and used one simple prompt: “Create me a web game from this image.” You give it a simple image like this, and suddenly you realize you can build: • a voxel map • an editor • tile animations • a playable browser prototype This is getting ridiculous.

This game is blowing my mind, a single player adventure where you can take pictures that change the entire game and it's environment...

Crossy road made $10M+ in 3 months without charging upfront With only IAP and ads Let that sink in 🤯 building a game like this was extremely complicated 5 years ago → 3D/2D models → Animation → Map design → Game loop and logic Now with Rork max you can solve all of that in 1 prompt With 1 prompt you get: →3D models →The animations →The map →and the game logic I made my own version of crossy road where you play as a lizard And all of this was added by Rork in 3 prompts Everyone is looking at apps But now it’s the time to build a million dollar video game

Can you believe this game is 100% AI engineered? Yes it took me 900 commits and 150 hours in one month... (and I have a day job) But it's a full 3D factory automation roguelite game with 10000s of entities running in a WEB BROWSER

Grok 4.5 in Grok Build is insane for 3D game dev🤯 I ran a detailed prompt using the /goal feature and I created this in only two prompts. Took roughly an hour. The model rigged all the enemy humanoids and made a fleshed out map and AI logic.

If i ever see you in Arc Raiders and i shoot on sight not being friendly. You can all blame this guy. Like i understand the goal of the game isn't to be friendly with everyone but when shit like this happens it just blows my mind. At the end of the day its a video game but do u really gotta be this much of a dick?

With GPT-5.5 coming Thursday, I had generated a beautiful star-destroyer game in Three.js A 3D game in Three.js. A space combat arena with procedural nebula shaders, seeking enemy drones, warp gates between sectors, combo multipliers, and fully synthesized audio. Single HTML file. No assets. Insane generations.

Yeah I wish Eternal Sonata gets a remaster so I can capture the game from my console instead of using my phone The battle system in this game is still fun to this day #CedEternalSonataPS3version

Let's walk through an imaginary apartment that exists in the mind of Gen-4. It's a video game but not like a video game. It's like a movie but not like a movie. It's like something else that feels like something else. This was all generated from just a single image using Runway Gen-4.

There is a better, more subtle way to include a trans character in your fantasy game that does not involve a performative apology and a lecture using parlance that has no place in a game like this. This is basically self-parody. It's a shame because the game is, imo, still quite fun.

Mind-blowing what you can build with zero coding skills today! 🤯 I’m designing my own 3D Pokémon-like browser RPG using Three.js & OpenAI (GPT-5.4). The barrier to game dev is officially gone, and I'm loving every second of it. 🎮✨ #NoCode #GameDev #AI

With Gemini 3, thanks to the model’s significant improvements in coding capabilities, you can build interactive 3D designed games with a single prompt. See how Gemini 3 can handle complex prompts to build richer game design and aesthetics:

Kimi K3 makes me feel like one prompt is enough to build a game. You can build a game console, plug in a cartridge, and play a game on it. I just played one of my fav game "Ace Attorney" on my computer!
