I've got a few. d("d)
Chrono Trigger - I was introduced to this through my stepbrothers, who insisted it was the best RPG EVAR. It's certainly one of my favorites. I enjoy everything about it, but the music really sticks out to me. One day, I'm going to pick this up for the DS, so I can play it again. ;_;
Tales of Symphonia - It was once part of my daily routine, I kid you not. Although the gameplay needs work, I just love the story and the characters. I could probably pick it up again and still enjoy it as much as I did in high school.
Persona 4 - A rather recent game to my collection, but still awesome. I really love the battle system and Social Links. The story could use less repetition at times, though.
