Retainers on the go! Could they possibly get technologically advanced?

[File2ish]

I can't remember where I saw it, but someone had modded their phone to play FFXIV.

I remember seeing that as well, though I'm pretty sure they made the phone a monitor to play the game. Phones wouldn't be able to play XIV natively taking into account hardware needed to actually run the game, a client built/converted to run on Android/iOS, and the need to access the servers.
