Have you spent hours of gaming, confident that you could have made the experience more enjoyable if you had designed the game yourself? We have some good news for you; now, you can make your own games!
We don’t mean simple snake games; we’re talking about full-fledged open-world RPGs. You can write questlines in seconds, build pixel art with prompts, and generate full characters, environments, and even gameplay logic, all with the help of AI.
This is a step-by-step guide to building your own game from scratch with AI.
And if school’s in the way, there’s a website to get your homework done online by experienced authors, so you can still aim for that A+.
What Kind of Games Can You Make Using AI?
Just how far can you go using AI to make your own game? The answer is: quite far. With the right mix of AI tools and a bit of creative drive, solo developers are building games that used to require entire teams.
AI won’t magically do everything for you, but it can absolutely handle the heavy lifting:
- Code generation
- Art prompts
- Dialogue writing
- Level design
And everything else you may need with the right prompt. Here is a deep dive into what you can make and how long it will take, either solo or with a small crew.
| Game Type | Examples | Time Estimate | AI Tools You’ll Use | What AI Can Help With | Pro Tips |
| Arcade / Mini Games | Snake, Flappy Bird, Tetris | 2-7 days | ChatGPT, GDevelop, Piskel, Construct 3 | Writing core logic, creating simple scripts, and generating level variations | For beginners and non-coders, this is the best place to start learning version control. |
| 2D Platformers | Celeste, Dead Cells, Hollow Knight | 1-3 weeks | Midjourney, Unity, ChatGPT, GitHub Copilot | Platform physics, enemy behavior, tilemap layouts, animations | Keep the level design tight. Use consistent art prompts for cohesion. |
| Visual Novels / Story Games | Doki Doki, Coffee Talk | 1-2 weeks | ChatGPT, NovelAI, Ren’Py | Dialogue trees, character bios, and branching plots | Use AI to generate custom character portraits & backgrounds. |
| Simulation / Tycoon Games | Stardew Valley, Game Dev Tycoon | 2-5 weeks | ChatGPT, Godot/Unity, Midjourney, Soundraw | Economic systems, item balancing, UI mockups | Test your loops early. AI can simulate player behavior for feedback. |
| Top-Down RPG / Small Open World | Undertale, bite-sized Skyrim | 1-2 months | ChatGPT, Unity, Scenario.gg, World Anvil | Quests, world lore, dialogue writing, and combat logic | Start with a vertical slice (one area, one quest) before expanding. |
Step-by-Step: How to Make Your Own Game with AI
Now, with the game idea in place, you need to start building. If you don’t have an idea yet, you can use step 1 to sketch one out for a game.
Step 1: Brainstorm Your Game Idea with AI
Define your game’s genre, setting, mechanics, and core loop.
Tool of Choice: ChatGPT (or any large language model)
You don’t have to start with a complete vision. Just toss in some keywords:
“I want to make a side-scrolling action game with space ninjas and giant ants.”
AI can help you flesh out:
- Game mechanics (dash moves, stealth kills, combo chains)
- Worldbuilding (who lives in this world?)
- Narrative arcs and level themes
You’re not writing a GDD (Game Design Document) from scratch, but simply riffing ideas.
Step 2: Generate Art and Assets
Create game-ready visuals, characters, environments, UI, and icons.
Tools: Midjourney, Leonardo.Ai, Scenario.gg, Daz
Start with character concepts:
“A robot ninja with a cracked mask and new age weapons.”
Then move to background art, UI buttons, weapons, and more. You can even maintain a consistent style by using the same prompts or uploading reference images.
Next, you will need art. Tools like Piskel or Pixelicious.ai can help, or you could train a custom model using Scenario.gg for game-specific styles.
Pro Tip: Save everything in layers or sprite sheets early on. It’ll save you time on your engine later.
Step 3: Build Levels and Worlds with AI Assistance
Generate levels, layouts, and environment logic in this step.
Tools: Unity + Unity Muse, and Promethean AI
AI-assisted level design tools can:
- Autogenerate terrain or dungeon layouts
- Place objects like platforms, doors, and enemies logically
- Suggest design iterations based on your theme
Even better, these tools work inside your engine, so you’re tweaking directly in Unity, not starting from scratch. Finally, let AI generate a basic map layout, then go in and “decorate” with gameplay moments.
Step 4: No-Code Gameplay Mechanics (or Almost No-Code)
Build the systems that make your game playable.
Tools: ChatGPT, GitHub Copilot, Unity Visual Scripting, and Convai
AI can generate working code for engines like Unity or Godot, or walk you through setting it up with visual scripting tools. Let’s say you want to add complex mechanics like double-jump or enemy patrol AI. Just describe it in plain English:
“Make the player jump again if they’re already in the air and haven’t jumped twice yet.”
You will need to do some debugging here. If you face an error during compilation, copy your error message into your LLM and let the AI fix it. Non-coders can always get a little professional help from experts on special platforms like Studybay for quicker results.
Pro Tip: Use AI to write item systems, health bars, cooldown logic, or even random loot drops.
Step 5: Playtest, Polish, and Iterate with AI Feedback
It’s time to test your game, fix what’s broken, and improve the overall experience.
Tools: ChatGPT, Unity Analytics, Rewind AI (if you’re fancy)
You can simulate user behavior with AI, for instance, “What would happen if the player just runs right past the enemy every time?”. You can also:
- Ask for UX feedback
- Rewrite the tutorial dialogue
- Balance numbers like XP gain, enemy HP, or coin drop rates
Finally, polish it. This basically requires you to repeat this loop. AI just speeds it up.
Pro Tip: Test one mechanic at a time. Use AI to isolate bugs and find smarter ways to guide players through the game.
Challenges & Pro Tips
AI tools are seriously leveling the playing field. They help solo devs write, design, and code faster than ever. However, it’s not as simple as pressing a button and publishing the game. Here’s what to keep in mind:
- Expect bugs; test often in small chunks to isolate the issue.
- Learn to use version control on Git.
- Keep art styles consistent with prompt templates.
- Build mechanics first, lore second.
- Use AI to write documentation, and get ChatGPT to explain your code in plain English.
- Real player feedback beats any AI-generated analysis.
Remember, AI will still make errors on long projects. So, make sure your prompts are clear and consistent.
Final Thoughts
You can now build the game you have always been dreaming of. It will be a steep learning curve, but AI will make it simple and easier to get done. Now all that you need to do is start!
