I must say I'm really enjoying this Final Fantasy IV port so far. Just reached Mysidia and yeah sure the gameplay is at a fixed 30 fps for fields and 15 fps for battles, but you get used to it after awhile and the gameplay of the DS version along with the augments make the game pretty fun. Plus the acheivements are spaced out pretty well and you get them all the time just by playing the game, but there seems to be a few really tough ones snuck in there for good measure also such as beating the new boss form the DS version Proto-Babil. I wouldn't know if it's worth it for everyone especially since the price is around 16$, but probably on a sale it's a decent playthrough if you want to relive nostalgia of a great Final Fantasy game.
