Besides the Persona/misc SMT games, which plenty of people have gone/will go to bat for, I'd say Tales of Berseria makes a good case. I was a big fan of Symphonia back in the mid 2000s and then none of the other Tales games really grabbed me after that.
Berseria doesn't have the strongest overarching plot, but the party dynamic is amazing. You're not really out to save the world as much as complete the singular task of getting revenge on the guy who ruined the main character's life, who the rest of society idolizes and adores. It feels like playing the likable mid-tier villains in a normal jrpg, rather than the clear-cut heroes. That was cool and new to me, as a big fan of the genre.
