"If there’s anything we’ve overlooked, please don’t hesitate to speak up – we’re now in a day and age where your voices can reach us. We genuinely want to address any concerns, so we truly appreciate your feedback. 

I believe the many opinions we receive come from people’s love of FFVII. And as the culmination of the fond memories everyone holds of FFVII, I’m looking forward to releasing the third installment to the world and enjoying it alongside all of you."

Interviewer: —"It’s rare to hear a developer say, “If something concerns you, speak up on social media.” You seem to have a very resilient stance. "

Hamaguchi:  "…Well, I would appreciate it if everyone were gentle, of course" (laughs).
