>>714937381 (OP)Absolutely, though see them as different games. For FFIV, there are so many versions you can go for - I'd recommend FFVI for PSP, Ultima for SNES (a fanhack) and DS. The 3D version is much harder than the other official versions of the game, but PSP has the most content. Ultima is a great senpai rebalance of the SNES version with a shitton of new bosses and content. Ignore the FFII version (original localized version) and the PS1 ver.
For FF3, you only really have 3 versions. NES, PR and the DS version. They're all worth playing as FF3 is great in all versions.
