Something I've never seen anyone mention even though it's public knowledge stated by Coco herself, is that Coco was banished from playing Sega games by Sega for God knows what reason. I believe this and only this is the entire reason why she is quitting. I've never played a Yakuza game, but Sonic Adventure 2 is one of my favorite games of all time. If someone told me I could never play it again, I'd tell them "Fuck you."
