Nutaku BGR didn't get new characters or story for an entire year. The content was there, the story had an extra 9 chapters worth. All that was needed was a translation.
Right until the end, maintenance occurred every 2 weeks with proper gacha and event changeups.
Now then, the one who was responsible for translating the content was...Nutaku. Look up SuperHippo and you'll see that localization wasn't the responsibility of the Japanese developers.
...Anyway, from your language that's practically arguing for the sake of arguing, it's pretty obvious you haven't even played BGR, why are you even on this thread anyway? Instead of kicking a dead game for the laughs, find a better use for your time.
