Yes it is! The first 2 games. It’s kind of an odd situation where the 2nd game is kind of a remake-ish retelling of the first game, sort of like Final Fantasy or Zelda, where it is different characters but same themes. I just thought of 2 more I could recommend! Grandia and Live a Live. Both fit nicely in Chrono Trigger’s orbit, though none are quite as good. Live a Live just got a low up and re-release recently too.
