There's supposed to be an Animal Crossing game for the mobile device last year, but at last reported it will not make its debut until March 2017. Since the said month is getting close, and Fire Emblem Heroes which was delayed together with Animal Crossing has been released. Maybe this app is coming soon. Unfortunately, there's not much information on what the game title would be, nor if it's a fresh title or a port from existing game. Until then, keep an eye for this app.
