So far I've found three versions of Moon over the Castle in my collection.
-Gran Turismo 2 version
-Gran Turismo 2 version remix (with synthesizers)
-"Orchestral" version
Okay, now it really feels like Gran Turismo!
This song is really special to me because I had the Japanese version of the first Gran Turismo about six months before it was released in the North America. Somehow it just appeared at my door ;-), and for the next three days, I only got up from behind my wheel to eat and use the bathroom. Of course I bought the U.S. version and played through it again. Was a little bummed that North American customers couldn't relish the beauty of the song and how it added to the experience. The Chemical Brothers song was great, but just not the same.
