Two localization vendors may over similar services, but the scope of their work can differ significantly. Some focus on core services such as translation, LQA, voice-over, project management, and culturalization. Others extend their coverage to include localized storefronts, ongoing community support, and additional publishing-related services. This means that the term “game localization vendor” rarely refers to the same service breadth.

Developers and publishers often compare partners based on language count, rates, or portfolios, but understanding exactly what tasks are included and who owns each stage is significantly more important. The International Game Developers Association (IGDA) highlights that localization can involve everything from translation and LQA to localized assets, UI adjustments, ratings, store content, voice implementation, and regional publishing considerations. Understanding the vendor’s scope, workflow, and deliverables is what enables developers to know exactly what they are getting end-to-end.

Before evaluating vendors, we first need to understand what tasks are included in game localization.

What Does a Game Localization Vendor Do?

A game localization vendor helps developers and publishers adapt a game for players in different markets. However, the scope of work can vary considerably from one vendor to another. This is why the term “end-to-end localization” should not automatically be interpreted as a fixed list of services. Developers need to look beyond the label and examine exactly what a vendor handles, what it delivers, and which responsibilities remain with the internal development team.

Game Localization Services

At its core, game localization transforms a game’s source content so that it resonates naturally within target markets both linguistically and culturally. This process relies on four core services:

• Translation & Editing: The foundational process of translating in-game text, dialogue scripts, and system UI while preserving original tone, context, and gameplay intent.
• Localization Quality Assurance (LQA): In-game testing conducted within actual builds to verify text length, line breaks, character rendering, UI overlap, and contextual accuracy.
• Voice-over & Audio Dubbing: Casting, recording, sound engineering, and audio mastering to provide localized voice tracks across various languages. 
• Culturalization: Assessing narrative elements, symbols, character designs, and regional sensitivities to ensure compliance with local regulations and cultural expectations.

Beyond these core offerings, full-service localization relies on critical supporting services. Project management ensures timeline tracking, resource allocation, and budget control. Localization engineering handles text extraction, file formatting, pseudolocalization, and build compilation. Marketing localization adapts store page descriptions (ASO), trailers, and promotional material. Post-launch support manages ongoing live-ops updates, community patch notes, and player feedback.

What Services Does a Game Localization Company Provide?

Not every vendor offers the same scope. Some may focus on translation, while others provide a more integrated workflow.  When comparing vendors, it helps to distinguish services, deliverables, and functions.

Not every game requires every service to the same extent. A narrative-heavy RPG may require extensive culturalization and multi-cast voice-over, whereas a fast-paced indie puzzle game might only need UI translation and targeted LQA.

Among these varied game localization service models and tailored requirements, translation and LQA remain the absolute foundation. Translation makes the content understandable, while LQA ensures it works correctly in the target language and game environment. 

The next step is to look more closely at how these two core services fit into the overall localization workflow. 

Game Translation and LQA Services: From Text Adaptation to In-Game Testing

Game translation and LQA services are distinct but complementary parts of the localization process. Translation adapts the game’s language for a target market, while LQA checks whether that language works correctly inside the game. Although they support the same goal, each requires different skills, workflows, and quality checks.

Game translation covers a wide range of content, including UI text, character dialogue, tutorials, quests, item descriptions, system messages, subtitles, and narrative content. The goal is not simply to convert words from one language to another. Translators must account for gameplay mechanics, preserving context, tone, and character personalities while relying on central glossaries and style guides to maintain terminology consistency across assets. Our guide to game localization vs  translation covers it in depth.

LQA takes the process further by testing the translated content in the localized game build rather than reviewing translated documents alone. As defined by the IGDA, LQA is structurally separate from translation, editing, and proofreading (TEP), marking the first time localized text operates within the actual game engine under real-time conditions. During LQA, testers evaluate the build for contextual accuracy, visual rendering, UI constraints, font behavior, and overall linguistic flow during active gameplay. In-game testing often uncovers errors that remain invisible in spreadsheets , including:

• Text overflow and truncation: strings breaking outside UI bounds or buttons.
• Placeholder bugs: unextracted code or raw variable tags ({0}) appearing on screen.
• Formatting errors: Bad line breaks or missing font glyphs rendering as empty boxes (tofu).
• Contextual misalignment: Dialogue tone clashing with character animations or gameplay situations.

The tangible deliverables produced across these foundational phases includes localized string files, glossaries, style guides, linguistic review logs, detailed bug reports with screenshot evidence, and verified retest results.

Once the text and visuals are ready, games that feature voiced dialogue require an additional localization process to preserve characterization and the audio experience. 

Game Voice-Over Localization Services: Bringing Characters to Life

Game voice-over localization services go beyond translating dialogue. They involve an audio production process that adapts, records, and tests spoken content so that localized characters sound natural while remaining consistent with the original game. Depending on the game and target market, some titles may require subtitles only, while others may use partial voice-over for key characters or scenes, or full voice-over across the entire game. Defining these requirements early helps determine the localization budget, casting needs, recording schedule, and technical specifications. Our comprehensive guide to video game audio localization explores the process in greater detail.

Script adaptation ensures dialogue sounds natural when spoken while preserving the original intent, character personality, tone, and emotion. Voice casting considers character traits, age, personality, speaking style, accent, and how well each voice fits the narrative. Voice direction then maintains consistency in pronunciation, pacing, emotion, and characterization across recording sessions.

Recording and post-production include editing, mixing, file naming, formatting, and preparing audio assets according to the game’s technical requirements. Subtitle synchronization and audio LQA are also essential to ensure dialogue, subtitles, character animation, and visual context remain aligned. During this phase, testers check for missing assets, incorrect timing, mispronunciations, line mismatches, and playback trigger failures.

The IGDA categorizes voice-over as a core stage in the localization workflow, covering script prep through final recording. Core deliverables include: 

• Localized voice scripts: Performance-ready scripts with pronunciation and timing notes.
• Casting records: Audition tracks, character briefs, and casting confirmations.
• Recorded voice assets: Mastered and named audio files built to technical specs.
• Audio QA results: Detailed reports confirming audio sync, mix balance, and playback alignment.

However, having the right language and audio does not automatically guarantee that a game will be well-received in every market; content must also be reviewed with the target culture’s context in mind.

Culturalization Services for Video Games: Adapting Content to Local Markets

Taking things a step further than translation and voice-over, culturalization services for video games look at how well a game actually fits into the culture, social norms, and politics of a new market. A solid cultural review digs into everything on screen, symbols, color choices, gestures, humor, religion, history, political themes, and character art, to catch anything that may feel out of place or accidentally offend players in different parts of the world.

While translation focuses on conveying linguistic meaning, culturalization evaluates the contextual relevance, appropriateness, and regulatory compliance of content within the target market. Depending on the findings of a cultural audit, adjustments may be applied to dialogue, character costumes, narrative arcs, environmental art, or seasonal event content. 

Developers should not assume that local reference or direct adaptations are automatically appropriate. Culturalization goes beyond basic localization to examine a game’s core creative choices and see how they land in different markets. To get this right, developers rely on native reviewers and real market research rather than relying on guesswork. 

The IGDA recognizes culturalization as a distinct phase of game localization, outlining key cultural variables that developers must evaluate during production, a framework detailed extensively in their Best Practices for Game Localization guide. Tangible deliverables from this phase include:

• Cultural review report: A clear breakdown of local sensitivities and content rules across target regions. 
• Risk assessment log: Categorized inventory of potential geopolitical, regulatory, and cultural risks rated by severity.
• Adaptation recommendations: Specific actionable guidance for modifying narrative, artwork, or audio assets.
• Review escalation list: Tagged elements requiring further decision-making from executive producers or creative directors.

These services do not operate in isolation; a cohesive workflow is required to connect all tasks, ensuring the final output is ready for integration into the game.

End-to-End Game Localization Process: From Project Setup to Final Delivery 

Managing an end-to-end game localization process is all about keeping every moving part aligned from setup to launch. A game localization vendor does way more than just translate text; they coordinate teams, manage technical pipelines, and run quality checks so every asset slides right into game build.

Game Localization Workflow and Deliverables

A clean game localization workflow and deliverables setup usually breaks down into four quick stages:

1. Pre-Localization: Analyzing requirements, locking in target languages, and prepping source files. The vendor sets up localization kits, glossaries, and style guides so translators get the context and constraints upfront.
2. Localization Production: Translators, editors, voice actors, and cultural reviewers do the actual adaptation work, handling text (TEP), voice-over, and cultural reviews based on your game’s needs.
3. Integration and LQA: Engineers import translated strings and audio back into the build. Native testers play the game to spot text overflows, visual bugs, or audio glitches, logging and retesting bugs inside the build.
4. Final Delivery: The vendor hands over clean string files, audio cuts, updated glossaries, style guides, LQA reports, and project docs.

When figuring out what to look for in a game localization company, don’t just rely on long language lists or cheap rates. Knowing how to choose a game localization vendor comes down to checking their real game experience, linguist quality, service scope, LQA capabilities, and technical support. Look for clear workflows, explicit responsibilities, and deliverables you can check at every phase. Extra services, like store page adaptation, marketing, community support, and post-launch updates, come down to your project budget and contract scope.
