I'll do GBA another time.
I've also just added Preparing for Action from Okamiden to my Word document I copied the list in the OP from. Should I update the OP?
Also... Okamiden is the sequel to Okami, a PlayStation 2 game that was ported to the Wii. In my music lists, I'll only count remakes for the new console if the music is significantly changed, so Okami's soundtrack will only qualify for a theoretical PS2 list. However, in the sixth generation, multiplatform games became more common, which begs the question... what list would multiplatform games go on? The first console they were released on? The console they were designed for?
I never thought I'd say this, but I'm glad that the GameCube port of Lunatea's Veil was cancelled, because there would be no ambiguity as to what the top spot
of said theoretical PS2 list would be.
