What set FF apart from DQ, PS1 and many of 80s JRPG is, FF1 had load of combat options like 60 commands and the battle system at glance looks original (of course it is copied to death), It isn't an ARPG nor 3D RPG (AKA first preson).

Of course, PS1 had a better character design than FF or DQ.

Personally, I am not into any of them. My favorite 80s games are XZR, Valis, The Scheme, Sorcerian, Zeliard, The Rogus, Diva and Warning Type 68.
