Chrono Trigger and it isn't close.
Looks like 100% of the forum agrees.
I can imagine being right very easily
I have more nostalgia for Trigger's OST, because I played the game itself over and over and over with my best friend when we were young. It's just ingrained in my brain as of that time.
But I like Cross' OST more.
Extra vote for Brink of Time, which was just totally my fucking jam for ages.
Hell yes. Came here to say this.
I vastly preferred Trigger. It evoked emotion harder than any game.
While I have many, many, many, many, many hang ups on Chrono Cross especially in regards to its relation to Trigger, the music is not one of them, Cross may just be the best OST of golden age Squaresoft.
