I'm trying to recall ...
Some game I read about a while back said they were going to use multiple languages. If your character got a translator then, and only then, would you hear all the game dialog in the language of your choice.
Such a thing wouldn't be too hard to implement as most games are translated into multiple languages anyway.
Wow, I hadn't though of it that way. Assuming that the game would only be voiceacted in one version, the English one, I thought it would be crazy to do the simultaneous translator thing. But seeing how the Witcher 3 has been dubbed in various languages, it could be like changing languages on the fly, you would be presented with the audiofiles for that dialogue in that language. Still, maybe CP2077 will only have an English version, but if it uses a similar philosophy... it could work.
