Theatrhythm Final Fantasy has leaped from the 3DS to iOS. The game can be downloaded for free (find it here), but songs are available as in-app purchases. It’s unfortunate that making this leap appears to be so easy for developers though, since it suggests the advantages of the 3DS might not be that dramatic. Am I reading too far into this? Or, if not, how could Nintendo make the 3DS more compelling for exclusives?
Edit: One big disadvantage of the iOS version is the cost of the additional content, so at least in this case, the 3DS version seems to be the best option for people who want the full experience.
