Chrono Trigger, being the first game I ever completed, and only being like 10 years old, makes the entire game nostalgic for me. But if I had to choose one song from that game, it's
Yearnings of the Wind. I remember I was blown away when I first heard it. Hard choice though, there's so many good songs in this game, I could be here all day.
Earthbound was the first RPG I played, but I got stuck a lot, so it took me until I was 12 years old to beat. I remember at the end I walked all the way from Saturn Valley with Paula to her home, and then walking all the way to Ness' home alone. Just reminiscing while listening to...
this song, I think? It doesn't quite sound how I remember, but that might be just because it was years ago.
Another game I have a lot of nostalgia for is Mother: Cognitive Dissonance, of course since I beat it at 13 years old. It's the only full-length RPG I've beaten twice. When I first saw the scene with Alinivar and his band playing
To the Future, it filled me with emotions I couldn't describe. What an experience to have.
