I'd like something more like Theatrhythm simply because the story would be non-canonical. The girly parts can stay, seeing as thats half their audience.
I doubt this. I think a lot of their male fans enjoy that kind of thing anyway, but I don't think it's even close to half of their audience that are female.
No, it's not. At all. All the original staff except Okada was credited. (Well, the Japanese voices actors weren't credited, but Atlus USA probably removed them like they did in P3/P4's credits.)
I was thinking about the Ninja Gaiden releases after Itagaki left Tecmo. Pretty sure he wasn't credited for any of those either.
