How to choose an AI game maker before you trust it with a game

Rick Vu, 9 October 2026

An AI agent drafted this piece under Rick's direction, as part of an experiment in AI writing. Every figure links to its source.

To choose an AI game maker, give each candidate the same small game prompt and spend an hour checking what happens after the demo. Check what it exports, who owns the result, whether the game runs without the vendor, how it handles multiplayer and payments, where the price jumps, and what you will have to disclose on Steam. A maker that passes those checks on your own prompt is a safer choice than the one at the top of a ranked list.

Rick Vu, who directs this site, builds Scoat, an AI-native game maker, so he has a conflict of interest in any article about choosing one. For that reason this page does not rank makers. It gives you a test you can run on any of them, including his.

Search for “best AI game makers 2026” and many of the pages that rank for that query are lists written by companies that sell a maker. A list like that can be accurate and still answer the wrong question. Most makers produce an impressive first scene from a short prompt. The differences show up later, when you want to change the tenth thing, ship to a store, or stop paying.

Give every maker the same prompt

Write one prompt before you open any tool, and paste it into each maker unchanged. Keep it small enough to finish in one session and specific enough to fail in a way you can see. For example:

A top-down 2D game. The player moves with the arrow keys and collects 10 coins.
Two enemies patrol fixed paths. Touching an enemy restarts the level.
Collecting all coins shows a win screen with the time taken and a restart button.

Then send the same follow-up edit to each maker:

After the player collects 5 coins, make both enemies 50% faster.

The first prompt tests generation. The second tests whether the maker can change a working game without breaking it. You will make the second kind of request far more often, so give it more weight.

For each maker, write down the answers to these questions:

• Did the game run on the first try?
• Did the edit work, and did anything else break?
• Can you open the code or the scene and see what changed?
• How many credits or how much usage did the two requests cost?

A maker that hides the project behind a chat window can be fine for a toy. For a game you plan to work on for six months, it is a risk.

Check what it exports

An export is the file or folder you can take away. Some give you a build for a desktop platform. Some give you project source that another editor can open. Some only give you a link to a page on their own site.

Read the export section of each maker’s docs, then try it. As of October 2026, the Summer Engine homepage lists Windows, macOS, and web export. Its FAQ says iOS and Android builds need that platform’s toolchain and signing, and console versions need platform holder approval. Compare a list like that with the platforms you actually need, and test each export yourself.

Ask these questions about each export:

• Does it include source code and assets, or only a compiled build?
• Which platforms can it target today, as opposed to “coming soon”?
• Can a standard engine or editor open the exported project?
• Does the export require a paid plan?

Read who owns the output

Ownership has two layers. The first is the vendor’s terms, which say what rights the vendor grants you and what it keeps. The second is copyright law, which decides whether parts of the output are protectable at all.

For the first layer, read the terms and the pricing page, not only the homepage. The Summer Engine homepage says “You own the code and assets you create.” A sentence like that is a good sign, and the terms are where you confirm it. Rights can also depend on the plan. As of October 2026, the Rosebud pricing page lists “complete commercial rights to your games” on its $30 per month 10x Dev plan, and its free and $15 plans do not mention commercial rights. If you plan to sell a game, the cheapest plan that grants commercial rights is your real starting price.

For the second layer, the US Copyright Office announcement of Part 2 of its AI report says AI outputs are protected only where a human author determined enough expressive elements, and that prompts alone do not count. The same announcement says that using AI to help, or putting AI material inside a larger human work, does not bar protection. In practice, your own design, edits, and arrangement carry the strongest claim. That report covers US law. Check the rules where you publish, and ask a lawyer before you build a business on the answer.

Turn off the vendor and see what still runs

Imagine the maker shuts down, raises prices, or closes your account next year. What happens to your game?

Work through it in order:

1. Export the project.
2. Open it somewhere the vendor does not control, such as your own computer or your own web host.
3. Run it with the network off, unless the game itself needs a server.
4. Check whether any part of the game calls the vendor’s servers while it runs.

The fourth step matters most for games with AI in the loop, such as characters that talk back. Those calls cost money every time a player uses them, and someone has to pay. Find out whether the bill goes to you, the player, or the maker, and what the game does when the bill stops. AI NPC cost per player works through that math.

As of October 2026, the FAQ on the Rosebud pricing page says Pro and higher plans let you download your project code and export a Windows build you can publish on Steam. If a maker’s docs never say how you leave, assume leaving is hard.

Ask about multiplayer and money

Multiplayer and payments are where a demo and a product split apart. A single-player prototype can run entirely on one device. A multiplayer game needs servers and a plan for players who lose their connection.

Some makers advertise multiplayer. The Summer Engine homepage has an “Add multiplayer” section, for example. Treat any claim like that as a test to run. Open the game on two devices and play together. Then ask who runs the servers, who pays for them, and whether the networking code comes with the export.

For money, list how you plan to earn and check each path:

• Can you sell the game on Steam or itch.io under your own account?
• Can you add in-app purchases or ads, and through whose payment system?
• Does the vendor take a share of revenue, or only a subscription fee?
• Do the terms allow commercial use on the plan you can afford?

If the only way to publish is a page on the vendor’s own site, the vendor controls your distribution. That can be fine for a jam game. It is a poor fit for a game you want to earn from.

Find the pricing cliff

Most AI game makers price by credits or usage limits. The pricing cliff is the point where your normal week of work costs more than your plan allows. A pricing page will not show you that point. Your own usage will.

During the one-hour test, note how many credits the prompt and the follow-up edit used. Multiply that by a realistic number of edits per week, then compare the total to each plan. As of October 2026, the Summer Engine pricing page describes its Pro+ and Ultra plans as “3x” and “20x” limits without stating the base amount. When a page gives multipliers without a base, ask support for the number before you pay.

Also check what changes when you downgrade or cancel. Does the game stay online? Do private projects become public? Do you keep commercial rights for games you already shipped? If the terms do not answer these questions, ask support and keep the reply in writing.

Plan the Steam AI disclosure now

If you plan to sell on Steam, you fill in Valve’s content survey before release. The Steamworks content survey documentation splits AI content into two kinds. Pre-generated content ships with the game and was made with AI tools during development. Live-generated content is created by AI while the game runs. For live-generated content, you must also tell Valve what guardrails stop the AI from generating illegal content.

That split maps onto the makers. A maker that generates your sprites and music gives you pre-generated content to disclose. A maker that puts a talking character in your game gives you live-generated content, and you need a guardrail answer. Ask the vendor what filters run on its models before you commit, because Valve will ask you.

Disclosure is common. Dataconomy’s report on Steam Next Fest counted 1,704 of 8,700 titles tagged as using generative AI, about 19.5%, in the Next Fest covered on June 17, 2026. Many developers are still wary. In the GDC 2026 State of the Game Industry report, 52% of industry professionals said generative AI is having a negative impact on the industry. Why game developers distrust generative AI looks at where that view comes from.

Run the whole test in an hour

Here is the hour, in order:

1. Write the prompt and the follow-up edit before you open any maker.
2. Run both in each maker, and note what broke and how many credits each request used.
3. Export the result and run it outside the vendor’s site.
4. Read the pricing page and the terms for commercial rights, code download, and what happens when you cancel.
5. If you need multiplayer, open the game on two devices.
6. Write down what you would disclose on Steam, both pre-generated and live-generated.

As an estimate, plan on about 15 minutes per maker for three makers, plus time to compare notes. Pick the maker whose weakest answer you can live with. A maker that wins the demo and fails the export test will cost you more later than one with a plainer first scene.
