This is a really good question SInce Inever really thought of it myself I just wented by what is and will allways be best still

Vagrant Story- The closet thing to Secret Of Mana and was the only other game that used this battle system besides Hybrid Heavan or Quest64.

Alundra PSX series - Was the alterative to Y's and Zelda at the time. When it went 3d the game itself was still just as fun. It was just amazing to see this game in action.

FF8- was a great improvment over FF7. The only reason this is better the fact after Midgar FF7 is pretty much meh. Also FF8 had only One Bahamut like it should be.

FF7- brought RPG games to the modern era or at least industrial era and basically was just FF6 revamped. I was also impressed by the transformation of etc character.

Personally I am not a PSX fan at all and the be RPG is not on the PSX. It is the Mother Series tied with Star Ocean/Tales Of Phantasia SNES. The PSX has alot of great games just not the gereatest and the only reason I picked Vagrant is the game reminds me of FF6+Secret Of Mana 3.
