So now I completely disagree with you.
First, there are tons of Japanese games with English fan translations. Someone had to do that too, it could probably be done in retrospect.
There is no need for direct communication between the two parties for translation, especially at a time when automatic translators reach a relatively high level. True, they have their faults, but everyone will understand that in the final, of course there are exceptions here too.
In addition, I think that even the translation is not absolutely necessary, thanks to adult games, I have expanded my vocabulary quite a bit. And I know a lot of people who learned decent English years ago thanks to computer games.
And it's not even about the number of immigrants from the East, these communities are quite closed in themselves, how many Chinese or Japanese, etc. forums are you active on? Or do you know someone who is active on them? They just don't have to mess with us and live for themselves.
But I've been a very bad prophet for most of my life, so maybe I'm wrong again.
