I guess none when you put it like that, but Takaki doesn't fit that criteria either?
Not really? Under Marvelous, his work at managing the Senran IP ( which extends to anime/mobile game/external & internally developed console projects) was considered strong enough that he not only got his own studio ( Honey Parade ), he was also working on another multimedia new IP?
Ultimately, I'd say purely from a track record of experience in these areas:
- studio head
- managing internal/external development of console games simultaneously
- managing multi-media aspects of game IP ( manga, anime, etc )
Takaki's record is solid enough. He's not proven himself on a mega-scale AAA project, nor has he shown that he has some sort of special 'personal touch' as a producer that elevates the works he's managed, but it's not a bad track record purely from a checklist perspective.
Ultimately, a role like GM and studio head are hired for their managerial and people-leadership skills first and foremost. How they delegate is more important than how they make.
