I have mixed feelings about the FF1 remakes, they eliminate the challenge which was the games main draw but at the same time the gameplay has been greatly balanced.

I think the FF3 and FF4 remakes are amazing and greatly superior to the originals.

I don't have a lot of experiences with FF4-6 ports, I usually just load up the original in an emulator.

All the 16-bit games with redrawn sprites look absolutely horrible.
