Animenewsnetwork posted an interview of Norihisa Kochiwa (Producer) and Tsunekiyo Fujisawa (handles the Hakuoki series). I’ve quoted the choice parts:
ANN: It’s rare to see a visual-novel "otome" game like Hakuōki released in North America. How do you think the game has done in the U.S.?
Kochiwa: Up until now, visual novel games in the U.S. were not accepted as “games.” The reason why we were able to release Hakuōki in the U.S. is because we had Aksys Games who understood Hakuōki and fans outside of Japan who supported it. As a result, our beautiful illustrations and story got into the users’ hands correctly, and we’ve received great reviews. I would like to express my thanks to those involved, along with the fans.
ANN: how do you think the market in North America is changing for Japanese visual novels? Will you consider releasing similar games in North America, such as Norn 9?
Kochiwa: Hakuōki was the first time we released an otome title in the U.S. However, the market is still very small, and I do not think it will be an easy path. For Norn 9, I believe the quality of the art and the story will satisfy U.S. consumers. If there are enough voices that request it, we would like to make your wishes come true. Please continue to support us!
Norn9 is a brand new otome game just released in Japan on May 30th. The license would be a bit steep seeing as it’s so new. Probably not doable. I may be wrong though.
