Just a little tid-bit in OPM about HDD:
These are the games in Japan that support HDD, and how:
FFX: HDD\'s stored data cache for faster load times.
Jade Cocoon 2: faster load tiomes + storing of monster creations.
Capcom vs. SNK 2: faster load times.
Atelier Lillie: faster load times.
A-Train 2001: storage of snapshots and level designs.
Beatmania 5th Style: faster load times.
Mostly faster load times, and some basic storage. Not all these games may support the drive in other countries through. We\'ll have to wait and see, promising though.
