Its pretty good...
GS2 was a pretty good game and this is the first remixes of the map themes I've heard on the portal thus far. This little medley is a little better than the original so I think you captured it nicely. Of course, it doesn't blow the pants off of the orig. cause they had such a high standard to begin with so yea, good job. However, you didn't include the theme that plays when you sail around on the lemurian ship, which was a big part of the later part of the game mind you, so you get a point shaved off for that. Otherwise, you did the themes justice here...keep it up.
J00 get 5/5 and 9/10.
