I am working through the Trails in the Sky series right now.
I finished FC (the original, not the remake) and it was just okay. It didn't really click in mjy head tbh and I wasn't sure why there was so much hype.
But I just finished SC, the 2nd chapter, and something just clicked about halfway through this game. And now I'm fully invested in this series.
So not quite the same game, but it's the same series and I think the story for this series is all interconnected so it's kind of just one giant game/story. But yeah, it didn't really click for me until the 2nd game.
