A game that feels made for its players will always beat one that feels translated. That is what video game localization delivers: a version of your game that reads, sounds, and plays naturally in each market. Done well, players never notice it. Done poorly, they stop playing.
This guide walks through how video game localization actually works, what drives the cost, and the pitfalls that trip up even experienced studios. Whether you are planning your first release abroad or scaling into new languages, you will leave knowing what the process involves and how to get it right.
Localization is a growth decision as much as a technical one. It opens your game to players who would otherwise pass it by, and it deepens engagement for those who can finally play in their own language, which is why it belongs in the release plan rather than at the end.
What is video game localization?
Video game localization is the process of adapting a game for players in another language and culture. It covers far more than translating words, since a game is an interactive product with text, audio, graphics, and rules that all have to make sense to a new audience.
You will also see this called game translation, though localization is the more accurate term, since it spans text, audio, cultural references, and platform requirements, not words alone. That scope includes the interface and menus, in-game dialogue, voice-over, on-screen graphics, in-game chat and community text, age ratings, and even the store listing. This is why it belongs under localization services rather than plain translation, a distinction we cover in localization versus translation.
The video game localization process
Localization runs best as a defined sequence, where each stage sets up the next and problems get caught early rather than at submission. The flow below shows how a game moves from code preparation to a market-ready release.
Internationalization
The groundwork happens in the code. Internationalization, often shortened to i18n, is what the W3C defines as the design and development of a product that enables easy localization, built in from the start rather than added later through expensive re-engineering. In a game, that means externalizing text strings from the code, supporting Unicode so every script displays correctly, and leaving room for text to expand. Skipping this stage is one of the costliest mistakes a studio can make, because every hardcoded string has to be found and pulled out later.
String translation and adaptation
Next, linguists translate the game’s text strings, from menus and tutorials to item names and dialogue. Context is everything here, since a short string like “Fire” could be a command, an element, or an action. Professional teams work with reference material and glossaries so the same term stays consistent across the whole game, keeping the voice and intent of the original writing rather than only its literal meaning.
Culturalization
Culturalization goes a step beyond language to adapt the content itself. Humor, symbols, gestures, historical references, and storylines that work in one country can confuse or offend players in another. This stage adjusts those elements so the game respects local norms and avoids content that could harm its reception or its rating.
Voice-over and dubbing
Games with spoken dialogue may need localized audio. This ranges from subtitles only to full voice-over and dubbing with native actors, which is more immersive but also more involved. Timing, lip-sync, and casting all factor in, so studios usually decide the audio scope early, since it shapes both budget and schedule.
Localization QA
Localization quality assurance, or LQA, tests the translated game inside the actual build. Linguistic testing confirms the text reads correctly in context. Cosmetic testing catches display problems, since translated text usually runs longer than the source: Microsoft’s internationalization checklist notes that English strings often expand by 40% when translated into German or Dutch, and the W3C points out that the shorter the string, the bigger the growth, which is how text ends up overflowing buttons and boxes. Functional testing confirms nothing breaks in the localized version.
Platform requirements and submission
Finally, the game has to meet the requirements of each platform and market. Consoles and storefronts review each game before release; Steam’s review, for example, checks that the build starts properly and that every feature listed on the store page is in it. Age ratings come from a different body in each market: the ESRB in North America, voluntary by law but required by all console manufacturers, PEGI across most of Europe, the USK in Germany, where a game without a rating may only be sold to adults, and CERO in Japan. Many digital storefronts issue several of these at once through the IARC questionnaire. Building compliance into the process avoids last-minute rejections that can delay a launch.
What drives video game localization costs
There is no flat rate for localizing a game, because the work scales with the project. Understanding the main cost drivers helps you plan a realistic budget before you request a quote.
The largest factors are the volume of text and the number of languages, since both multiply the work directly. Audio raises cost sharply, as voice-over and dubbing add recording, direction, and talent on top of translation. The depth of LQA matters too, because thorough in-build testing takes time but prevents costly post-launch fixes.
Other drivers include reworking graphics that contain text, meeting platform and rating requirements, and your timeline, since turnaround is one of the factors that shapes a quote. Live-service games add ongoing cost, as each content update needs localizing in turn. Machine translation can speed up high-volume, low-risk text as one step in a workflow that ends with a professional linguist, while creative, context-heavy game text stays with human linguists from the start.
Common video game localization pitfalls
Most localization problems are predictable, which means they are preventable. These are the mistakes that most often reach players, and each one traces back to a step handled too late or skipped entirely.
- Leaving internationalization until the end, so strings are hardcoded and have to be dug out of the code
- Translating strings without context, which produces wording that is grammatically fine but wrong in the game
- Forgetting text expansion, so translated text overflows buttons, menus, and subtitle bars
- Skipping LQA, which lets display bugs and mistranslations ship in the live build
- Translating cultural content literally, so jokes fall flat and references confuse or offend
- Ignoring platform and age-rating rules until submission, triggering rejections and delays
- Treating localization as a final task rather than planning for it from the start
The thread running through all of these is timing. Localization handled early and alongside development avoids nearly every one of them, while localization bolted on at the end invites them.
How to choose a game localization partner
The right partner does more than translate text, so look past price to capability. A strong provider brings linguists who understand games and play them, not only general translators, because gaming language and tone are their own skill.
Beyond that, check for built-in LQA, experience with platform and rating requirements, and the capacity to handle ongoing updates for live-service titles. Confidentiality matters too, since unreleased games are sensitive. We offer human-led localization across 130+ languages, covering in-game text, voice-over and dubbing, and testing, and you can see how we work with software and gaming companies on our technology and software page.
Frequently asked questions
These are questions studios ask that the guide above does not already cover in full.
What languages should I localize my game into first?
A common starting point is FIGS, which is French, Italian, German, and Spanish, often called EFIGS when English is counted in. Japanese, Korean, Simplified Chinese, and Brazilian Portuguese are frequent next steps. The right order depends on where your target players and revenue are.
Do indie games need localization, or is it only worth it for big studios?
Indie games benefit too, and you do not need every language at once. Many small studios start with subtitles in a few high-demand languages, then expand as the player base and revenue grow.
Can we use community or fan translations instead of professional localization?
Fan translations can build goodwill, but they vary in quality and often lack review, consistent terminology, or confidentiality. For a commercial release, professional localization protects both the player experience and your unreleased content.
What do you need from us to start localizing a game?
Usually, the text strings in editable resource files, plus context like screenshots, a character or style guide, and notes on tone. The more context you share, the more accurate and consistent the result.
