I know everyone has that one RPG they fell in love with that will always have a special place for them.
Maybe it was never popular. Maybe it was a love it or hate it and had mixed reviews. Maybe it was a product of nostalgia and the time of your life you played it.
For me it was Saga Frontier on the PSX.
Box Art
A game where you pick one of multiple characters and play thru the same game world on each one completing a different quest and seeing things from a different angle.
People would say the story is sparse, for me it was enigmatic and mysterious. People would say the battle system was obtuse, too difficult, or required too much grinding. I loved the challenge and getting wiped by it as a younger version of myself who wasn't ready for that level of difficulty, slowly figuring it out just made it all the more epic.
What's your game?
Threads of Fate/Dewprism. It's an action RPG with two protagonists so you have to play it twice to get the full story. It was actually one of the first JRPG or JRPG-adjacent games I ever played. Still, it's hard to explain why it left such an impression on me. The story isn't particularly deep and it's not particularly difficult, except for the part where it becomes a platformer for some reason, and I don't think I ever actually finished it as a kid, probably because of the platforming section now that I think about it. But for some reason whenever I feel nostalgic about old games this is the one I always go back to and play through.
