With this tool you can easily translate your game or application into any language supported by Google Translate API, the tool uses Google Translate to Translate any text you want to the language you want, it also enables auto translation to the user’s system language so you don’t even bother targeting a specific language all what you need to do is to call one of the translation functions then to handle the result when it finishes.

Nice!
Im not that much of a fan of Google translate, it messes up too many times… But this will open up the asian market, I think a lot of people here won’t be able to make a chinese version of their product, so even if the translation is a bit weak, it would still open up a huge market!!
A new update will be available soon :), version 1.1 will be released after review by unity (maybe today) and will include the following features:
1- Import\Export
2- Custom Translations(user specified)
3- Bake Google Translations and modify them
4- disable\enable Google translations and override it with your own translations and when not supplied use Google translation if enabled.
5- Exchange between projects and other users.
7- Full API
8- Stream your translations to reduce size and have only one deployment instead of multiple deployments or but your translation file in the resource section.
Stay tuned 
OK, it has been released http://u3d.as/content/mixed-dimensions/game-translator/1Bf
Google translate is nowhere near accurate enough to provide a decent translation of a single paragraph, let alone an entire game’s script.
if you haven’t the read post about the update for version 1.1 then i guess you need to read it because you can set your own translations and if you want you can either bake google translations and modify any errors or even make it all online so it reduces the size with streaming options, there is different opinions regarding this issue but what we do provide is a mix of both so you can use your own translations alone, google translations alone or mix of both
