“I resigned from Square Enix at the end of April,” “While I cannot share the reason right now, I hope to be able to discuss it when the time comes. As for what I’ll do in the future, I’m already 55 years-old, so I may as well retire.”
He may of only retired from SquareEnix, but is still making money from his SquareEnix stocks and other investments like selling his Sonic the Hedgehog Antiques and collectibles. I feel he most likely have enough money to retire at 55 since Sonic the Hedgehog is very popular which help him become very rich.
