South Korea now requires AI content labels in games
South Korea's Framework Act on the Development of Artificial Intelligence took effect on January 26, 2026. It's the world's first comprehensive AI law, and Article 36 has direct consequences for game developers everywhere. Any AI-generated content in a game sold in Korea, whether that's NPC dialogue, character art, or background music, must be labeled "AI-generated."
Overview of South Korea's AI Basic Act and its scope
What the law requires
Article 36 mandates a "duty to label generative AI" content. Game developers must clearly mark any content created with AI tools using watermarks or notices. This applies to illustrations, voice lines, story text, localization, background music, video sequences, and audio effects. Partial AI use counts too. If you used an AI tool to generate a texture that a human artist then refined, the law still expects disclosure.
The intent is to protect users' right to know what was made by a human and what wasn't. But game developers have raised concerns about breaking player immersion. Putting "AI-generated" labels on NPC dialogue in a fantasy RPG creates an odd experience.
It applies to foreign studios
The law has extraterritorial provisions. Global platforms like Steam and Epic Games must designate domestic Korean representatives and comply with the same requirements as Korean companies. If your game is available to Korean players, you're covered regardless of where your studio is located.
There's a one-year grace period before penalties kick in, so enforcement starts in early 2027. But the compliance work needs to start now for studios with Korean distribution.
"Permit first, regulate after"
One notable aspect: the law includes a "permit first, regulate after" principle for experimental AI applications. You don't need pre-approval to use AI in development. The government is using a task force approach, refining policies based on real-world deployment feedback rather than trying to anticipate every scenario upfront.
Steam narrows its AI disclosure
Separately, Valve updated Steam's AI disclosure policy in January 2026. The change draws a clearer line between what needs disclosure and what doesn't. "Player-consumed" content, meaning assets that ship in the game or are generated during gameplay, requires disclosure. Development tools like code assistants, debugging software, and AI-powered dev utilities are explicitly exempt.
Valve's reasoning: efficiency tools used during development don't change what appears on screen for the player. Around 8,000 Steam games disclosed AI use in the first half of 2025 alone, an 8x increase from roughly 1,000 for all of 2024.
The EU is next
The EU AI Act hits full enforcement on August 2, 2026. Penalties go up to 35 million euros or 7% of global annual revenue, whichever is higher. The EU requirements will apply across all 27 member states, creating an even larger compliance surface than Korea.
Between Korea's law, Steam's updated rules, and the approaching EU enforcement deadline, AI disclosure in games has gone from a niche compliance topic to an operational requirement for any studio with international distribution.
