Leaving a sinking ship? Do we have their twitter reasons of why they left? Do they have twitter in Japan? If not what is the social media equivalent?
Like I have said before, Square Enix has far too long focused on the Square half of the equation. Enix had some great IPs in the 1990s. Try and recreate those for a change. Maybe you can keep devs this way instead of losing them by endlessly tunnel vision focusing on the next Final Fantasy game.
