not retro but i only played 4. it's harder than the original us release and has some voice acting. jrpg's still arent really worth playing tho imo

4 on DS is pretty cool, worth playing if you want an extra challenge.

This is an unpopular opinion, but I love the version of 3 even more than the NES one. It's got a ton of charm.

Both of them are very different in terms of gameplay compared to their originals. FF4's main appeal is the higher challenge, while FF3's is in job balance reflecting the later FF games with job systems (jobs never become obsolete, they're simply different playstyles).
Storywise they add a lot of extra scenes. FF4's are interesting, but FF3's are just filler garbage.

FF3 on NES is the way to go. It's the best RPG on the system and one of my favorite of all time. The DS one is gay bobblehead bullshit.
