Well, I wouldn't know about their (really) early games, but I became a fan of the Tales series because of Vesperia- It's the first game that made me stop watching anime for 6 weeks in a row! Not even WoW could do that!
That said I'm sick and tired of reading about their newer games because they aren't out in English or because I don't have the right console- I REALLY hope to play this game
!
P.S - Any word about the character details?
