I'm surprised I haven't commented on this before!
I checked out this mix ages ago because I was familiar with the music from SF1 and 2. I loved it! This is a chill piece with an interesting progression and a lovely, lovely synthy sound to it.
But since then I've played Sword of Hajya - the original Shining Force Gaiden 2 for the Game Gear, and there was one tune on that that was my particular favourite - amazing, just amazing. I didn't recall for sure if this ReMix was arranging the same source material - and sure enough it is! It's a very, very creative take on it too.. So good!
