I think I read somewhere about the 360 version being over several disks, as they are using the game fully to the PS3 capabilities. I havent realy played many, I have played Kingdom hearts, seen Advant Children, I got X2, I was quite obbsesed with playing it for a length of time, but got distracted, it kind of confused me, Why would I want to get one of them to sing for combat instead of something that does damage.
