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.
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.
I think the one I have the most nostalgia for is Destiny of an Emperor. The main boss theme is instantly transporting for me. That 8-bit Capcom sound is so iconic.
Final Fantasy IV is what truly got me to fall in love with the genre, though. It was one of my first 16-bit games, so I was blown away by the graphics and especially the music.
