“Final Fantasy, being one of Square Enix’s very important franchises up there with Dragon Quest and the Kingdom Hearts series – when we do begin development, we do approach multiple platforms, multiple companies, about releasing the game. And when you approach them, they’re going to come back to us with their offers.”
The team and Square Enix then consider all those offers and decide what will be best for the project. In this case, Square Enix liked PlayStation’s offer best; it doesn’t hurt that PlayStation and Square Enix have a decades-long relationship resulting in various Square Enix exclusives on PlayStation consoles.
