For the PS1 alone.
Once upon a time
Xenogears (MY FIRST RPG EVER OWNED, PLAYED AND BEATEN, ichosethatoverff7andgaveff7tomysister >____> now she's an ff addict.)
Breath of Fire 3 (BOF 4 was alright but not as cool...I need to reby BOF3)
Chrono Trigger (re-released for the PS1, I beat it on SNES, but I'm just a fan.)
Star Ocean The Second Story (Fun game overall)
Valkyrie Profile (FTW! working on hard mode)
Legend of Mana (Interesting approach and the first time I REALLY considered replay value without knowing what replay value was...well from this and Valkyrie Profile).
Brave Fencer Musashi (BRAVE F*ING FENCER MUSASHI! How could you not...continuing)
Recent Buys (last 4 years or so)
FFTactics (I did not get too far into it, it's a recent buy)
Vagrant Story (great presentation. I need time to play through)
Chrono Cross (I have yet to give my appraisal of it, but the graphics are welcomed through nostalgia. I wanted it long ago and I recently ordered it within a year)
Castlevania: Symphony of the Night (not quite the RPG but seriously fun)
Alundra (great game so far. Frustrating puzzle elements but great game and music)
Final Fantasy IV, V, & VI (I was after VI and Chrono Trigger from the beginning. On separate accounts, IV and V came along for the ride. I wonder if they have FFIII)
Games I Still Want
Legend of Dragoon (One of my friends still has that since its release. And I saw it in a store 5 or so miles from me and my place of business)
Jade Coocoon (I forgot why I was fascinated with this game but then I was curious)
Saga Frontier (See above)
Grandia (See above)
Lunar Silver Star Story Complete (It just seems like a great game. I've always been curious about it).
Legend of Legaia (I heard it played like Xenogears. I played the demo then. It was alright but not enough to move me to buy it for some reason. 2D sprites were still cooler w/martial arts than 3D at the time so I dunno)
Parasite Eve (Played a demo of it. Seems fun & interesting. Once upon a time)
