He's a diva to the public, but I'm curious how he is to work with professionally. I think the guy's actually very rogueishly charming in his online persona. He just hasn't plain directed anything in a while, mostly just supervising direction, but he's still been involved in good stuff with regards to Bayonetta 3 or Astral Chain.
Still, though, it's been a while, but I think he has a very solid foundation of ideology for his direction in games, I'd trust him to direct something else, but maybe he's not interested in that anymore.
