Live A Live, if you want a pretty nice varied experience. It does a lot of things you don't typically see in RPGs.
Anywoo, I'm surprised you bounced off Star Ocean Second Story ... Otherwise, Etrian Odyssey III or Labyrinth of Galeria if you want to look a bit into dungeon crawlers (lots of good Indies too on that front).
SMT V Vengeance is a pretty good one coming up too.
