AI Game Assets in 2026: Copyright, Steam Disclosure, and Platform Compliance for Indie Studios

The Three-Layer Problem for Indie Studios Using AI Tools

If your studio is using AI tools like Scenario, Leonardo, Suno, or ChatGPT to generate art, music, dialogue, or code for your game, you're navigating three converging legal obligations simultaneously. First, can you actually own and enforce rights in AI-generated game assets? Second, what must you disclose to the platforms that distribute your game — Steam, Apple App Store, Google Play, and rating boards like the ESRB? Third, what must you tell players directly, and when?

These aren't hypothetical questions anymore. Steam's AI disclosure policy is actively enforced, with nearly 8,000 games disclosing AI usage in the first half of 2025 alone — up from roughly 1,000 in all of 2024. Games have been flagged, delisted, and forced to remove AI-generated content after community backlash. Meanwhile, the U.S. Copyright Office has issued two parts of its three-part AI report, and courts have affirmed that works generated entirely by AI cannot be copyrighted. The stakes are real, and the compliance landscape is shifting fast.

We've written previously about what game studios actually own when they use AI-generated assets and the copyright and platform policy landscape after the 2025 Copyright Office report. This guide focuses on what has changed in 2026 and what indie studios need to do now to stay compliant across all three layers.

Layer 1 — Copyright Ownership of AI-Generated Game Assets

What the Copyright Office Has Said

The U.S. Copyright Office has been clear and consistent: works generated entirely by artificial intelligence are not copyrightable because they lack human authorship. This principle was affirmed by the D.C. Circuit Court of Appeals in Thaler v. Perlmutter, where the court held that human authorship is a constitutional requirement for copyright protection. The Copyright Office's AI initiative page tracks all three parts of its report, the registration guidance, and key registration decisions.

The Office's Part 2 report, published January 29, 2025, addresses the copyrightability of outputs created using generative AI. The core finding: "whether human contributions to AI-generated outputs are sufficient to constitute authorship must be analyzed on a case-by-case basis." Critically, the report concluded that prompts alone do not provide sufficient control over the AI's output to constitute authorship. In other words, writing increasingly elaborate prompts to refine an AI-generated image is not the same as authoring that image.

The Office's registration guidance, issued in March 2023, requires applicants to disclose AI-generated content in their works and to disclaim any purely AI-generated material. In the Zarya of the Dawn decision, the Office allowed copyright in the human-authored text and the selection and arrangement of images in a graphic novel, but revoked copyright in the individual AI-generated Midjourney images. In Théâtre D'opéra Spatial, the Office denied registration even though the applicant claimed over 600 text prompts and Photoshop modifications, finding that prompt-based generation — even with extensive iteration — does not constitute authorship of the expression the AI produces.

What This Means for Your Game Assets

For indie studios, the practical implications are significant:

• Purely AI-generated art, music, or dialogue cannot be copyrighted. If your character sprites, background music, or NPC dialogue lines were generated entirely by an AI tool with only prompt-level human input, you likely cannot register or enforce copyright in those individual assets. Anyone could theoretically copy and reuse them.
• Human modifications outside the AI environment may create copyrightable elements. If an artist takes an AI-generated image and makes substantial manual modifications in Photoshop — not just prompt-based tweaks — the resulting work may contain copyrightable human authorship. The Copyright Office has acknowledged this path, though each case turns on its specific facts.
• Selection and arrangement of AI-generated content can be copyrightable. The compilation of AI-generated assets into a larger game — the level design, the narrative structure, the arrangement of visual elements — may be protectable as a compilation, even if the individual AI-generated components are not. This was the outcome in Zarya of the Dawn.
• AI-assisted code sits in a gray zone. Code generated by AI coding assistants like Copilot or Cursor may or may not be copyrightable depending on the degree of human control. We've addressed this in our guide to registering AI-assisted code with the Copyright Office, but the short version: treat AI-generated code as presumptively uncopyrightable unless a human developer substantially modified it.

The bottom line: assume that purely AI-generated assets are in the public domain unless and until you can demonstrate substantial human creative control. Build your IP strategy around the human-authored elements of your game — the code you wrote, the designs you manually created, the narrative you authored — and treat AI-generated content as a supplement, not a replacement, for protectable expression.

Layer 2 — Platform Compliance: Steam, Apple, Google Play, and Rating Boards

Steam's AI Content Disclosure

Valve announced its AI disclosure policy in January 2024 and has significantly refined it since. The current rules, as documented on Steamworks, require developers to disclose AI usage in two specific categories:

1. Pre-Generated AI Content: Any content created with AI tools that ships with the game — artwork, character models, voice acting, narrative text, sound effects, or marketing materials visible to players. Developers must verify that such content does not include illegal or copyright-infringing material and must provide details about what was generated and how.

2. Live-Generated AI Content: Content generated in real-time during gameplay — AI-driven NPC dialogue, procedurally generated textures, or adaptive storytelling systems. For this category, developers must implement guardrails preventing the AI from creating illegal, offensive, or inappropriate content. Failure to do so can result in game removal.

Importantly, Valve clarified in early 2026 that behind-the-scenes AI development tools are exempt from disclosure. If you use AI coding assistants, automated bug-detection, or other productivity-enhancing AI tools that don't produce content players see, hear, or interact with, you do not need to flag your game with an AI disclosure. The policy focuses on player-facing content — what players actually experience.

Valve has also introduced a player-driven reporting mechanism: users can flag AI-generated content they believe violates Steam's policies directly through the Steam Overlay. This community-driven approach means that even after launch, your game remains subject to AI-content scrutiny from your player base.

The disclosure obligations are retroactive in practice: Valve has required developers of already-released games to complete the AI content survey when submitting updates or new content. If your game was released before the policy and you used AI-generated assets, you should be prepared to complete the disclosure when you next interact with Steamworks.

Apple App Store

Apple's App Store Review Guidelines require that apps using AI-generated content clearly indicate when content is AI-generated and must not use AI to deceive or mislead users. Developers must also disclose in their privacy nutrition labels if the app uses AI to generate content that could be mistaken for real people or events.

Additionally, Apple's guideline 5.1.2(i) requires explicit user consent before any personal data is transmitted to a third-party AI service. The consent UI must name the specific AI provider, describe the purpose of the data transfer, and offer an opt-out path that doesn't degrade non-AI features. For game studios using cloud-based AI for live-generated content (e.g., real-time NPC dialogue that sends player input to an external LLM), this consent requirement applies directly.

Google Play

Google Play's AI-generated content disclosure rules became enforceable on April 15, 2026. The policy requires a visible label on any user-facing content generated by a generative AI model — text, image, audio, or video. The label must appear in the app interface adjacent to the generated output; a disclosure buried in a privacy policy or store listing does not satisfy the requirement. Google's policy uses the phrase "readily visible and accessible to users."

A July 15, 2026 policy update extended the labeling requirement to third-party AI integrations. If your game passes player input to an external LLM or image-generation API and displays the result, your game must label that output — even when your code is a thin wrapper around another provider's model. The compliance responsibility runs through you, not the API provider.

Minor violations (missing labels, inadequate placement) result in a warning and 7 to 14 days to fix. Major violations — generating harmful, deceptive, or exploitative content without safeguards — can proceed directly to suspension without a warning window.

ESRB and PEGI Rating Boards

The ESRB's ratings system evaluates games through a content questionnaire completed by publishers. As AI-generated content becomes more prevalent in games, rating boards are grappling with how to classify and label it. The ESRB has begun tracking AI-related content through its ratings process, and the IARC (International Age Rating Coalition) system — which powers ratings on Google Play and other digital storefronts — includes questions about AI-generated content in its content questionnaire.

For indie studios, the key takeaway is that AI-generated content is not exempt from the ratings process. If your game includes AI-generated art, dialogue, or live-generated content, you should disclose it in your ratings questionnaire just as you would any other content. Misrepresentation in the ratings process can lead to penalties, including re-rating or removal from storefronts that require ESRB compliance.

Layer 3 — Player-Facing Transparency

Beyond platform-specific requirements, there's a broader expectation of transparency that's emerging from multiple directions. The EU AI Act's Article 50 mandates disclosure of AI-generated or manipulated content (including deepfakes), enforceable by national market surveillance authorities. The FTC has signaled that deceptive use of AI-generated content can constitute an unfair or deceptive practice under Section 5 of the FTC Act. And player communities themselves are increasingly demanding — and enforcing — transparency about AI use.

The practical approach for indie studios is straightforward: when in doubt, disclose. If AI generated any content your players will see, hear, or interact with, tell them. This doesn't require a legal disclaimer on every asset. A clear, concise statement in your game's about screen, credits, or store page — "This game uses AI-generated art for background textures and some character portraits" — satisfies most transparency expectations and builds trust with your community.

Studios that have tried to hide AI use have faced significant backlash. When Jurassic World Evolution 3 disclosed AI-generated character portraits, the community reaction was strong enough that the developers removed the AI elements entirely. The lesson is not that AI use is inherently problematic, but that concealing it is. Transparent studios that disclose their AI workflows upfront tend to face far less community friction than those that try to slip it past players.

Actionable Next Steps

If your indie studio is using AI tools in game development, here's what we recommend you do this quarter:

1. Audit your AI usage. Catalog every asset in your game — art, music, dialogue, code — and flag which ones were AI-generated, AI-assisted, or fully human-authored. This inventory is the foundation for every compliance decision that follows.
2. Complete Steam's AI content disclosure. If you haven't already, fill out the AI content survey in Steamworks for both pre-generated and live-generated content categories. If you have a released game with AI assets, be prepared to complete this at your next update.
3. Implement Google Play's AI labeling. If your game generates content at runtime using AI — including through third-party API calls — build visible "Generated by AI" labels into the rendering components for each AI output type. Don't put the label in a settings screen; put it adjacent to the content.
4. Build Apple's consent flow for third-party AI. If your game sends player data to an external AI service, implement a consent gate that names the provider, describes the purpose, and offers a meaningful opt-out.
5. Document your human creative contributions. For every AI-assisted asset you intend to claim copyright in, document the human modifications you made outside the AI tool. Keep project files, version histories, and notes on your creative decisions. This evidence is what you'll need if you ever try to register copyright or defend against infringement.
6. Add a player-facing AI disclosure. Put a clear, honest statement about your AI use in your store page description, credits, or about screen. Transparency is cheaper than backlash.
7. Review your AI tool licenses. Check the terms of service for every AI tool you use — Scenario, Leonardo, Suno, ChatGPT, Midjourney, and others. Some grant commercial usage rights; others restrict them. Some claim ownership of outputs; others disclaim it. Know what you actually have the right to ship.
