How to make a game with AI
There are three ways to make a game with AI. A prompt-to-game platform such as GDevelop, SEELE AI, Makko AI builds a playable game from a description, with no code. An AI assistant inside a real engine (Unity, Godot, GDevelop) gives you more control and store exports. A coding agent such as MCP for Unity, Summer Engine writes the code for you in any engine. Beginners should start with the first option.
Step 1: Keep the first game small
AI tools are best at small, focused games: one core mechanic, one or two levels, a clear win or lose condition. Write a one-paragraph description, for example "a 2D platformer where a fox collects acorns and avoids hedgehogs, with three levels." You'll reuse it as your first prompt.
Step 2: Choose your route
Route A: Prompt-to-game platforms (no code)
You describe the game and the platform generates it, including code, basic art and hosting. It's the fastest route to something playable and usually runs in the browser. The trade-off is less control and fewer export options. Best for beginners, game jams and prototypes.
Route B: AI inside a game engine
Engines such as Unity, Godot and GDevelop now have AI assistants or agents built in, or available as plugins and MCP servers. You get a real project that can ship to PC, mobile and consoles, and AI does much of the setup and scripting. See AI for Unity, AI for Godot and AI for Unreal.
Route C: A coding agent plus any engine
General coding agents can build a game from scratch, for example in Godot, Phaser or plain JavaScript. They also connect to engines through MCP servers. This route gives the most control and needs the most comfort with code. See AI coding tools for game development.
Step 3: Generate the core loop, then iterate
Start with your one-paragraph description, play the result, and fix one thing per prompt ("make the jump higher", "add a score counter"). Small, specific requests work much better than rewriting the whole game.
Step 4: Add art and audio
Replace placeholder art with consistent assets. See how to make game art with AI, the best sprite generators and 3D model generators. For sound, see music, sound effects and voice.
Step 5: Check rights, then publish
Before you publish, confirm each tool you used allows commercial use on your plan. Our tool pages show this. Browser games can go on itch.io or your own site. For Steam you'll need a desktop build, and you'll have to disclose AI-generated content.
