Can you provide a source for this? I'm very curious, as I grew up speaking Tok Pisin, and played some Riven, and looking up cutscenes online I can't make sense of any of the Rivenese (well, the foreign language bits, I don't know if it's Rivenese or not), at least not in https://youtu.be/-rjfyfuijrc or https://youtu.be/smOzKs1hauM.
