Riviera: the Promised Land for the GBA is a beloved game of mine; of all the games I've played, it's the one with the most heart. That being said, it has some great music, and this track is probably my favorite. Aside from being good enough to listen to for hours, it's an unusual track in that it uses a 6/8 time signature. (FYI, for those who know my infamous wizard Mage Cierra,
her namesake belongs to this game).
It should be noted that the game actually came out originally on the WonderSwan Color, then was later ported to GBA and PSP. Here's the three different versions of the song for comparison:
WSC version (comparable to the GBA version):
GBA version (the best in my opinion, here unlooped):
PSP version (not as inspired, but still worth a listen):
