IGDA warns inconsistent crediting can hurt Nintendo workers’ careers

Accurate crediting is not a vanity issue in games. For Nintendo workers, it is part of the employment record that can determine who gets hired, promoted, or trusted on the next franchise project, especially when work crosses between Kyoto, global offices, and outside agencies.

The International Game Developers Association sharpened that argument with its March 13, 2023 update to its Game Crediting Guidelines, the first major revision in a decade. Alongside the guidance, IGDA released an open-source crediting toolkit for Unreal and Unity, signaling that credits should be treated as a standard production workflow, not an optional finishing touch. Its own survey showed how broken the system still is: 51.3 percent of respondents said they never, seldom, or sometimes receive official credit, and 83.1 percent were unsure or said their employer or client had no credits policy.

That matters at Nintendo because credits are one of the few durable proof points workers carry from project to project. A programmer, QA tester, localization specialist, or producer can point to a visible credit line years later; without it, the work can disappear from the career record. In a company built on long franchise lineages, the difference between being named clearly and being omitted entirely affects more than pride. It shapes who can demonstrate experience to future employers and how outside partners judge a studio’s fairness and maturity.

The pressure point is especially sharp in localization. In July 2024, external translators said Nintendo did not list translators from external agencies in game credits, and that the practice also kept them from listing those titles on their CVs. The projects named in that reporting included The Legend of Zelda: Tears of the Kingdom, Animal Crossing: New Horizons, Super Mario RPG, and Paper Mario: The Thousand-Year Door. The agencies involved included Localsoft and Keywords, and some translators said they were asked to sign 10-year nondisclosure agreements, further limiting their ability to show the work they had done.

Nintendo has also faced criticism over legacy credits in remasters. After Metroid Prime Remastered launched in February 2023, former Retro Studios developers criticized the decision not to include the original staff’s full credits, with Zoid Kirsch and Jack Mathews both objecting to the omission. Nintendo later drew fresh criticism over Donkey Kong Country Returns HD in January 2025, when the original Retro team again was not individually credited.

For Nintendo, the lesson is straightforward: credits are labor infrastructure. If the company wants workers, contractors, and partners to build portable reputations across an industry that moves fast, it needs rules that are documented, reviewed, and applied the same way every time.
