I agree, they do look good, but I think I like the platinum ones anyway...after all, it's not what the discs look like, it's their content.....you can't play a game just admiring the graphics in the surface of the disc!!!!
Yeah, speaking of which, I was playing it today, and to be honest, there's everything on the UK ones.......well, everything Niai pointed out anyway, but, I do know this, there's only about half the fight sequences and battles in the UK and European versions. The Japanese version has loads more fighting..(on the world map).
