Sonic CD’s regional soundtrack variation still gets talked about but Shinobi Legions/Shinobi X’s not so much.
Which do you prefer?
Shin Shinobi Den and Shinobi Legions (NTSC regions)
Shinobi X (PAL regions)
I love both soundtracks but overall I give the edge to the PAL version despite having experienced the NTSC one many years earlier. I still prefer stage 7-1 harbour music in Legions, though.
