Final Fantasy 4: The After Years is out today on iOS and Android, just in case you're still curious as to what happens after the events of the original 1991 classic. Although if your curiosity is really piqued, get ready to shell out your wallet; it costs $15.99.
If this new handheld version of the FF4 sequel sounds a bit pricey, there are some alternatives. You can still pick up the game as a downloadable title on Wii for a mere 800 points ($8). You can also pick it up for your PSP as part of Final Fantasy 4: The Complete Collection for close to the same price.
