I typed "Square Enix" into the iOS app store search box and holy crap, Squeenix is flooding the place with mobile games. ...and most of them look pretty good! Apart from the rereleases of FFs 1-7+T,Theatrhythm, SoM, CT, TWEWY, and DQ series (all nice in their own right!), there's also FFD, FFRK, Crystal Defenders, Song Summoner, the Chaos Rings series, Symphonica, Hills and Rivers Remain, Triple Triad, and some F2P ones that look decent, Drakenrider and this Heavenstrike Rivals thing.
There's also All The Bravest, but you can't win 'em all. Guardian Cross is also some kind of F2P Gacha based game with nothing but pandering half-naked ladies all over the advertising...
Here's hoping that all this mobile stuff is making them money hand over fist and they will translate FFD2. I really want that game in English, watching Shun play it in Japanese is not enough.
But yeah, gonna give this Heavenstrike Rivals thing a try.
