A remake of 1990's Final Fantasy 3, based on the DS version, is now available on Google's Android operating system, boasting "3D visuals and story sequences only for Android," as well as improved browsing functionality for the monster bestiary and new designs for the Job Mastery cards, according to the game's listing on Google Play.
The port will set you back $15.99 and requires that your device runs Android 2.2 (Froyo) or newer. Alternatively, you could buy the iPhone version, Famicom version for about the same price, or the DS version for about $40. You could also go back in time and prevent the Wonderswan Color port from getting informally cancelled, but that might require significantly more effort/less eBay.
