The music is probably the one element that stands out the most to me in this game. It has a fantastic soundtrack, just like Chrono Trigger. But Cross has more orchestral music thanks to CD technology.
Chrono Trigger's soundtrack is very orchestral, made all the more impressive from the fact that it is being generated by a chip. You can clearly tell a lot of the instrumentation though. I think the only other 16 bit title to get such an orchestral sound was Super CastleVania IV.
