I imagine they knew the iOS version was coming a long time ago and wanted to save SOMETHING as incentive to buy the iOS version. Without those exclusive characters, I don't think anyone already with the 3DS version would buy the iOS version.
THAT I'm not sure of.
Just how many iOS owners even know of Theatrhythm Final Fantasy? Would they know too that the iOS stuff was exclusive? It's not as if iOS owners are squeeing in delight for being so entitled anyway.
It's not just this game that has a redingdangdonkulous amount of stupid in it's AppStore reviews. It's quite common to have people complain about things that can be solved by doing something as involved and demanding as actually reading an app's description. Then there's the "this game should be more like this other game", "make this game run on my 1st gen iPad" when it's just not possible and (my personal favorite) the "I HATE YOU SO MUCH HOW DARE YOU PUT YOUR APP ON SALE AFTER I BOUGHT IT! YOU WERE OBVIOUSLY WAITING FOR ME TO BUY IT TO PUT ON SALE! I DEMAND A REFUND AND I HATE THAT I SPENT A WHOLE DOLLAR ON A GAME THAT WAS FREE FOR AWHILE".
Seriously, if you ever have a bad day just look through reviews in the AppStore. You're sure to find something someone posted that so stupid it'll make you feel better just knowing you're not as brain dead as some people. If you're not into that you can usually look at the new apps and can usually find a hilariously badly translated app description. We're talking full blown Backstroke of the West-style mistranslations. Awesome.
