Next-Level Video Game Localization

Game Localization

Keeping the story intact, no matter what language.

In the localization of video games, you need to have extensive knowledge of the source and target language and the relevant culture, as well as experience and familiarity with different game genres. With access to a vast pool of human resources located all over the globe, SunFlare can support you in making your game a worldwide hit. While taking painstaking efforts to ensure that the story line stays the same, we localize elements such as the character names, items and place names so that the player can enjoy the game as if it had never been translated from another language.

Ensuring that the final product is immaculate.

Localization QA

Say sayonara to unnatural translations and careless mistakes.

After the in-game text has been compiled, our linguists—who are always native speakers of the target language—play through the game while monitoring the translated text. The linguist checks for errors, overflowing text, unnatural expressions, bugs, irregularities and inconsistencies, and then reports or fixes them. It can be difficult to get the localized text to match the intended tone of the game without playing it, but it is simply not possible in most cases to play the game while translating (simship has now become the norm). Therefore, it is crucial to see the text in its proper context and add the finishing touches to ensure that the final result is perfect.

Focus Group Testing

Can’t decide whether to release overseas? Already released to a foreign market, but haven’t got the desired results?

If the above situations apply to you, then maybe you should try conducting a focus group test. We will gather a user set that matches your needs, have the users test play the game and then get them to complete a survey. We can translate all of the necessary materials and hand them over to you so that you can determine which step to take next.

Pre-Release Focus Group Test

Before release, identify any risk factors through surveys and see if your game will attract a broad consumer base in the target market.

Focus Group Test

While your game is in development, send off your alpha or beta build to a specified user set in your target market for them to play through and identify any points that need to be re-examined.

Post-Release Focus Group Test

Not reaching your forecast revenue targets (IAP, ARPU, etc.)? Verify where your users are dropping out, determine the reasons why, and then fine-tune your game.

Voice Recording

Spice up your game with unique and charismatic voice talent.

Japan’s seiyu (voice actors) are world-renowned. SunFlare has direct access to their world, from famous voice actors (perfect for lead roles) all the way through to up-and-coming talent (suitable for a variety of support roles). Men, women, children, seniors, and monsters—we will book the best matching voice actors for your project. Please note, however, that all bookings and recordings take place only within Japan.

Extra Service

We can arrange for our Japanese localization coordinator to sit in on the recording session to facilitate on-the-fly revisions to the script.
