As AI generation technology advances, many users without programming knowledge can easily create various programs and games. However, this has also led to many copyright issues. Therefore, to prevent users from asking AI models to reproduce copyrighted IP content, Anthropic recently added related restrictions to its AI platform Claude, and this has also heavily affected many AI games that are still in development.

This decision has already directly affected a creator who plans to use “vibe-coding” to build a Pokémon fan game. Not only that, by the time this policy took effect, he had already invested thousands of dollars and nearly a hundred hours into this project.

In a recently releasedPostIn it, creator Big Kid Nation said that Anthropic has officially implemented new safeguards for copyrighted IP, which has led the Claude model to start refusing the various related prompts he needs to make the fan game Pokémon Stadium 2D. Previously, the creator said that since the project began he had been investing $2,000 a month into it, spending 10 to 14 hours a day learning and polishing, and had not received a single cent through platforms such as itch.io or Patreon.
As a result, Big Kid Nation also pushed back strongly against some players calling Pokémon Stadium 2D “AI garbage,” stressing the immense effort he had poured into the project and his passion for the Pokémon series, while making clear that he would not be slowing down because of it.


According to the new policy statement released by Claude, starting with the latest version, Claude may not be used to “recreate specific existing games.” Although the gameplay style used in Pokémon Stadium 2D is indeed not copied from any existing Pokémon game and it also uses many community-made Pokémon assets, the IP itself is still protected by copyright, so various restrictions began to apply to its development.
In follow-up responses, Big Kid Nation confirmed that the team will continue using vibe-coding to develop Pokémon Stadium 2D, because its members are actually strong advocates of AI technology. However, they emphasized that the reason behind this is not “laziness,” but that it allows them to produce the best results. Even so, the team’s headcount continues to grow. In addition, the producer confirmed that Pokémon Stadium 2D is still on track to launch this December.
