The Importance of Style Guides and Glossaries in Game Localization

One of the most overlooked yet essential aspects of game localization is ensuring consistency throughout the game. That’s where style guides and glossaries come into play. A consistent translation creates a more engaging experience for players and makes navigation smoother.

What Do We Mean by Consistency in Game Localization?

Imagine playing a game where a key character is referred to by different names in various parts of the story. Where in-game instructions use different terms for the same action or where in-game dates are written in different formats. Inconsistencies like these break immersion, frustrate players, and can even impact gameplay. Forget engagement—it’s a usability issue.

Examples of inconsistencies game localization

Inconsistent localization can lead to:

• Confusing terminology, making it harder for players to follow objectives.

• Mismatched tones, which create an uneven narrative experience.

• Gameplay errors, such as misinterpreted instructions. 

• Loss of identity, where key names, slogans, or catchphrases aren’t uniform across translations. 

•  Formatting issues, like inconsistent date formats that can cause players to miss out on special deals.

This is why among the best game localization practices there’s the use of style guides and glossaries. 

What is a Style Guide in Game Localization? 

A game localization style guide is a document that outlines rules and references for translators to follow when localizing a game. It helps maintain a consistent tone, formatting, and style throughout the game. A well-built style guide typically includes:

• Tone and voice: Should the dialogue be formal or casual? Is the humor dry or exaggerated? Should contractions be used?

• Formatting rules: How should numbers, dates, times, and currency be presented?

• For example, without a style guide, one translator might make a character sound overly formal, while another might use slang, creating an inconsistent personality. 

Usually, the style guide is built by the client together with the localization provider.

The Role of Glossaries in Game Localization 

A game localization glossary is a list of key terms, character names, item names, and other crucial terminology with their approved translations. It ensures that specific words and phrases remain consistent across the entire localization process. A glossary should include:

• Character names and titles: Prevents the same character from having different names in different parts of the game.

• Item and ability names: If a spell is called “Shadow Burst” in one scene, it shouldn’t suddenly become “Dark Explosion” in another.

• UI terminology: Ensures standardized translations for menus, buttons, and notifications to make navigation easier.

• Lore-specific terms: Covers unique words that are essential to the game’s universe, such as invented languages, factions, or mythical creatures.
