The Legend of Zelda: Oracle of Seasons and The Legend of Zelda: Oracle of Ages, probably. They are a couple of the first video games I have ever played, and are to this day, still two of my all time favorite games. Moreso than any of the other Zelda games. The music brings back so many memories of wasted hours and late nights under the covers with a flashlight.
Some other ones that are very dear to me, would be Golden Sun and Golden Sun: The Lost Age. Incredible games, with an interesting story, fun characters, and again..amazing music.
