Okay, a lot of people have asked similar questions, and I'm sorry but the answer is 'no.'
As for the reasons, I've actually explained this many times before:
- No one on the team is familiar with this new language, so we can't guarantee the quality of the translation.
- The game currently has close to 500k English words, and it's still being updated—that number will only keep growing. It's a massive amount of work.
- If we add support for a new language, we would need to maintain and update it continuously for years to come. That's really challenging, because people's enthusiasm naturally fades over time.
- The way Ren'Py handles translations means that if a single line of English text is modified, the corresponding translations in other languages become invalid. To put it simply, if I fix a typo in an English line, I have to re-export the Chinese and Japanese translations and re-translate the affected sentences one by one. Supporting more languages would mean even more workload, and my energy is limited.
So for now, I really don't plan to consider adding support for any new languages.
