Legend of Zelda: Ocarina of Time." What a combination! Star Wars and Zelda. That would be an epic game or movie!
I've always loved that tune from the game, and in fact, I liked it so much I taught myself to play it on the piano by ear and from memory. The game has a lot of other good tunes, too, and the plot actually involves using music to help on the Hero's quest. It's a refreshing and novel use of music in a role playing game.
There are some other video games with good music, too. Currently I'm re-playing Dragon Quest VIII: Journey of the Cursed King. In Japan, there has been a tradition of taking music from this series and performing it with an orchestra. In this installment, the music is symphonic within the game, providing an excellent background while playing. It's one of the few games I know that has real symphonic music.
Some other games with music I enjoy include Breath of Fire, Chrono Trigger, Chrono Cross (especially the opening tune, Time's Scar), Final Fantasy VI, Final Fantasy X, Secret of Mana, Shadow of the Colossus, Xenogears, and of course just about any of the Legend of Zelda games. There are some excellent symphonic albums and piano compilations out there, especially for the Final Fantasy series. Check them out! And let me know if there are any video games with music you really like, too.
