And that's why Itagaki is suing for 148 million yen (US$1.5m) on his way out. Not only that, but Itagaki also says Yasuda "made demeaning remarks" about him to other employees, affecting his status at work, giving him "significant emotional distress" and "worsening [of his] personal relationships and work environment."
In his statement, Itagaki said there won't be any more Ninja Gaiden or Dead or Alive games from him, as the rights are retained by Tecmo. This will surely come as a huge disappointment to fans.
Update: Fixed a wording discrepancy.
