How to make a video game with AI

By the end of this guide you will have a small playable game, built from a written idea, with a clear picture of which parts AI can make for you: the code, the art, the 3D models and the backdrops. No single tool does everything well, so most people combine one tool that makes the game with others that make the assets.

To make a video game with AI, start small: describe one simple game, generate a playable prototype, then improve it in rounds. This guide explains which kind of tool to use for each job and compares seven from our Coding category and neighbouring ones.

Key takeaways

• Pick one small game idea, generate a playable prototype first, and add art and 3D assets only after the core loop is fun.
• The main decision is the route: a browser game maker that builds the whole game from a prompt, or a game engine such as Unity or Roblox with AI helpers for scripts and assets.
• Free tiers are small, for example Rosebud AI's Free plan starts with 8,000 credits and Meshy's Free plan has 100 monthly credits.
• Check asset licences before you sell or publish. Some free plans require attribution or limit commercial use.

What you need before you start

• One simple game idea. A game you could explain in two sentences, such as a one-button runner or a top-down maze.
• A browser, and optionally a game engine. Browser game makers need nothing installed. Unity, Unreal or Roblox Studio are needed for the engine route.
• A free account with one or two tools. Start with one and add others only when you need them.
• Time. A first playable prototype takes under an hour. A game worth sharing takes days or longer.
• Difficulty. Easy for a browser prototype, moderate to hard once you move into an engine.
• Rights awareness. Know who owns the output of each tool and whether your plan allows commercial use.

Which kind of AI tool fits this job

Think about which part of the game you want help with.

A browser tool that makes the whole game. Rosebud AI turns a plain-English description into a playable 2D, 3D, voxel or multiplayer game with art and sound, running in your browser on Three.js. You refine it by chatting, the generated JavaScript can be read (in-browser code editing needs Indie Dev or higher), and you can remix published games.

AI help inside an engine. Haddock turns a text description into a script for Roblox, Unity, Unreal Engine or Minecraft, with modes such as NPC, module and GUI. Bezi is an AI agent workspace for development teams with a focus on Unity, where pages and rules keep the agent's work consistent.

Art and animation. Ludo.ai generates animated sprite sheets, game art such as backgrounds, icons and UI, 3D models, sound and music, and helps with game concepts. Its web app is the main route, with a CLI, MCP server, API and Unity plugin on higher plans.

3D models and environments. Meshy turns text or images into textured 3D models with rigging, animation and plugins for Blender and Unity. Sloyd generates 3D assets from text or images, with parametric templates, rigging and plugins for Unity, Unreal and Blender. Skybox AI generates 360-degree environments from text prompts, with cube map and HDRI exports for game engines.

Step 1: Define a tiny game

A small scope is the difference between finishing and abandoning.

1. Write the game in two sentences: what the player controls and how they win or lose.
2. Pick the platform: browser, Roblox, or a downloadable game in Unity or Unreal.
3. Cut features until one core action remains, such as jumping, collecting or dodging.
4. List the assets you need, but do not make any yet.

Check it worked by being able to describe a full play session in under a minute.

Step 2: Choose your route and tools

You end this step with a toolset that matches the game you described.

1. For a quick browser prototype, start with a prompt-to-game maker like Rosebud AI.
2. For Roblox, Unity or Unreal, pair your engine with a script generator such as Haddock or an agent workspace such as Bezi.
3. Decide which assets you need AI for: sprites, 3D models or backgrounds.
4. Check the free plans against your needs using the comparison table below.

Check it worked by listing each tool and the one job it will do.

Step 3: Generate a playable prototype

The goal is something you can play, even if it looks rough.

1. Paste your two-sentence description into the game maker or into your engine's scripting helper.
2. Ask for the simplest version of the core action first.
3. Play it, and write down what feels wrong in plain language.
4. Ask for one change at a time, such as slower enemies or a different jump.

Check it worked by playing from start to finish without the game freezing or breaking.

Step 4: Add art and animation

Placeholder shapes are fine until the game plays well, then replace them.

1. Choose a consistent style before you generate anything.
2. Generate characters and items. Ludo.ai makes sprite sheets from one character image or a text prompt, and Rosebud AI can also generate sprites and animations inside its game maker.
3. Check that every sprite is the same size and style, and fix mismatches.
4. Import the files into your game and test them in motion.

Check it worked by seeing the new art in the running game without gaps or flicker.

Step 5: Add 3D assets and environments

Only do this for games that need 3D.

1. Generate props and characters from text or an image. Meshy and Sloyd both offer text-to-3D and image-to-3D.
2. Check the polygon count and, where the tool allows, reduce it. Sloyd lets you control polycount and topology.
3. Export in a format your engine accepts. Meshy lists FBX, OBJ, GLB and others, and Sloyd lists GLB, OBJ and FBX.
4. Add a backdrop. Skybox AI exports cube maps for game engines such as Unity, Unreal Engine and Roblox.

Check it worked by dropping each asset into the engine and viewing it from several angles.

Step 6: Playtest and fix

Other people will find problems you cannot see any more.

1. Ask two or three people to play without instructions.
2. Watch where they get stuck, and do not explain.
3. Ask the AI to fix specific problems, pasting any error message exactly.
4. Test again after each change so a fix does not break something else.

Check it worked by having a new player complete the game without help.

Step 7: Check licences, then share

Make sure you are allowed to share and sell what you built.

1. Read each tool's licence terms. Meshy's Free plan uses a CC BY 4.0 licence that requires attribution, and Rosebud AI's commercial rights start on its 10x Dev plan or higher.
2. Keep a list of which assets came from which tool.
3. Publish to a shareable link or your chosen store. Rosebud AI offers one-click publishing to a shareable link.
4. Credit the tools or assets where the licence asks you to.

Check it worked by being able to point to a licence or plan that covers every asset.

Common mistakes to avoid

• Starting too big. Ambitious ideas produce half-finished prototypes. Fix it by building one core action first and adding features only when it plays well.
• Generating art before the game works. Assets made for a game that later changes are wasted credits. Fix it by using placeholders until the core loop is fun.
• Mixing styles. Tools produce different looks, and a game assembled from several can feel messy. Fix it by choosing a style first and regenerating assets that do not match.
• Ignoring licences. Free plans can limit commercial use or require credit, as Meshy's free plan does. Fix it by reading the terms before you publish or sell.
• Trusting generated code blindly. Scripts may run but behave oddly or be inefficient. Fix it by testing each change and asking the AI to explain what a script does before you keep it.

Frequently asked questions

Can I make a video game with AI for free?

Yes, within limits. Rosebud AI has a Free plan that starts with 8,000 credits and needs no card. Meshy's Free plan gives 100 monthly credits, and Sloyd's Guest plan gives one AI 3D generation per day. Free plans cap output and often restrict commercial use.

Do I need to know how to code?

Not for a browser prototype from a game maker like Rosebud AI. For Roblox, Unity or Unreal you will meet code, and tools such as Haddock write it from a description. You still need to test it and understand roughly what it does.

Can AI make the whole game?

AI can make a playable prototype, scripts, sprites, 3D models and backgrounds. Design, balance and polish still take your judgement and playtesting, and the pieces usually come from more than one tool.

Which tool is good for Roblox?

Haddock lists Roblox script generation, and Skybox AI lists cube map exports for Roblox. Check each vendor's current documentation for what works with Roblox Studio before you commit to a plan.

Can I sell a game made with AI assets?

It depends on the plan and the licence. Rosebud AI's commercial rights need 10x Dev or higher, and Meshy's Free plan needs attribution. Read the terms of every tool you used, and get legal advice if the game is a business.
