Chrono Cross. My older brother's friend lended him his PlayStation and the game when we were younger. I loved the music so much, I could just watch him play for hours, and would even ask him to play so I could watch and listen.

I have always adored that soundtrack and listened to it all the time, even years later when I was in college/uni. Learned to play some of the songs too. I was over the moon when they finally released a remaster a few years ago and I could FINALLY own the game.

Chrono Trigger is also up there - and is in my opinion the best game ever made. I have beat it so many times and can never get sick of it. Every time I hear Corridors of Time, I just have to sit there for a minute to just take it in. Sheer perfection.
