"Golden Axe The Music" comes out on February 21st, 2008. This three disc set includes the music to Golden Axe, Golden Axe II, Golden Axe III, Golden Axe The Duel, and Golden Axe The Revenge of Death Adder. Looks like it's going to include both the Arcade and Genesis versions of the first game, and both the Arcade and Saturn versions of The Duel. It also says there will be new arrangements exclusive to this release.
It's gonna be one of those Sega Direct only releases but I'm assuming VGM World and/or Play-Asia will stock it as well.
P.S. Did I mention I f---ing love Sega? Now all we need is a Sonic 1-3, Knuckles, and 3D Blast set!
