I've played Phantasia (S.Fam, GBA, PS1), Destiny (PS1), Eternia (PS1, PSP), Symphonia (GC), Legendia (PS2), Abyss (PS2), Vesperia (360), Innocence (DS), Graces (PS3), and Xillia (PS3). My least favorite by FAR is Destiny on the PS1. That game is like a slower, jankier Phantasia with too many characters, most of them uninteresting or rote. Garr was my favorite, but I usually like the "sarcastic older guy" characters anyway. My favorite is a tough choice between Phantasia (my first, and a classic RPG in every sense) and Vesperia (excellent main character, pretty solid combat and quests). I didn't dislike Xillia as much as other people seemed to, but it's probably because I enjoyed the combat and customization so much.
