Famitsu recently featured an interview concerning SNK HEROINES ~Tag Team Frenzy~ , which included discussion from Art director Yusuke Amano, sound director Mayuko Hino, and director Kaito Soranaka. You can see a few snippets of that interview below, with translation courtesy of NintendoEverything.
On picking characters for the roster
Soranaka: I decided while discussing it with the game staff. There are the core characters that are already popular, characters we’d like to see become popular in the future, and even some inclusions that will surprise the fans… those are the three categories we have. Of course, there are still lots of great Heroines left, and just because they don’t appear in this game doesn’t mean we have written them off altogether.
On including Terry
Soranaka: Well, as Terry is the face of the SNK series we thought we’d make him a woman and have him in this game too!
Amano: First off the plan was for him to have the body of a woman but for his voice to stay the same. But, when we saw it for real, it was horrible! (laughs) Because of that we decided to go with a female voice, but finding the right female voice was tough, and we went through a lot of auditions.
On potential for a sequel
Soranaka: I think it would be nice if we could release a sequel every time there is a new KOF game, and to have one game that is raucously fun alongside a more traditional title. With that aim, I would like to carry on with the series.
