I recommend The Legend of Dragoon for the Plastation 1. It has graphics of the same level- or better than - Final Fantasy IX, with the best CGs on the Playstation. But be careful with this game. Although I think it's the best rpg on the Playstation, there are people who hate it (though I don't know why). -> 4 discs

I also recommend Vagrant Story, also for the PSX1, a Square game with a strong story, but it does have some violence, so if u don't like it, stay away from it. Oh, yes, the battle system is different from FF. I think it's called real-time battle or something (someone correct me if I'm mistaken). -> 1 disc
