It was a very good read & liked the details from the interview. I'm very curious about the additional modes & part of the $15 extra detail (I'm wondering what about the extra). I'm loving the details with allowing the best players to show off the game for high level perspective.
I think Team Ninja handles female representation is handle pretty well (not perfect and there are details I think they would need to work on when it comes to DLC choices) and gender equality does need work & improvements. I agree that everyone has their own taste when it comes to beauty or females, which can change by time & culture. DOA should have its own fantasy & presentation. I might take a look at their new IP Ni-Oh, which I'm glad their doing something new.
I remember when Alpha-152 has the one move while she was floating when pressing P would dive at the opponent tripping them & can do it multiple times which did get fixed in DOA5U. Not every fighting game will have perfect balance, but fighting games should mostly be about players knowledge & skill not how overly strong the character are when it comes to balance. I agree to respecting the character's uniqueness is the most important thing for DOA. Comeback mechanics is something that is about how its executed & how its handled. Focusing on balance along with examining opinions/feedback is proper way to go, I do hope for the best.
