Cyberpunk 2077 developer CD Projekt RED has discussed the possibility of having NPCs talking in their own, original languages, made clearer by your character’s translator implant. It’s just a possibility at this stage, but the studio is considering it.
In an interview with dubscore.pl, CD Projekt RED’s Sebastian Stepien said, “Decisions are not yet made, but we are thinking about some kind of system which could tell more about the game world.
“The idea is to record everything in its original language. If there are, for example, Mexicans in the game, they will speak with slang. All performed by Mexican actors. Then a player could try a translating implant, and according to its level, he will get better or worse translation.”
when other companies think how to implement mictrotransactions into their RPG in the less obnoxious manner CD Projekt thinks how to innovate RPGs a bit.
Also while it's not a completely new mechanic (I'm sure some obscure RPG from ancient times did it) it's execution that matters. If they make people speak spanish/french/cantonese and then run subtitles it would be cool.
Also if I was in their shoes I wouldn't tell anyone about this mechanic because it's easy to implement. But I think people are too busy with microtransactions these days so CD Projekt don't have to worry.
