Prior to co-founding Valhalla Studios, Itagaki used to work at Team Ninja, where he developed Ninja Gaiden and Dead or Alive. Despite the fact he resigned from Team Ninja years ago, Itagaki is still rather attached to the Dead or Alive series, which he helped create, and it looks like he isn’t happy with the way the more recent games have turned out.
In response to a fan complaining about Dead or Alive 5, Itagaki stated: “I have started to find how/what I can do for my daughter/DOA. Straightly speakin’, my daughter was totally ruined, spoiled. I can’t/shouldn’t avert my eyes from that fact. Many DOA fans here are crying, I will do something for DOA after I finished Devil’s Third.”
Itagaki was part of Team Ninja owner Tecmo until 2008, following which he left the company and sued them for unpaid bonuses. Ever since, he has had less-than-flattering things to say about the company, including one story about how he was tricked into releasing Dead or Alive 2 before it was complete.
