Atelier Iris series is a good choice, but be warned the second one kinda drags in certain points because when you play as Viese she is really only used to gather items to give to Felt.

Grandia is great too (and my next favorite RPG series after BoF). The entire Grandia series outside of Parallel Trippers and Digital Museum can be had on PS1/PS2, but the port of Grandia 2 on PS2 is pretty bad. Grandia Xtreme has IMO the best battle system but the story is severely lacking. Grandia 1 has maybe the best story in the whole series and a very endearing cast (the graphics, music, and gameplay are no slouch either).

I'll be honest and say I'm not a fan of Grandia 3. Too much Squenix influence IMO. However I'm in the minority, so.....
