You're a funny character. I doubt it would there would be that many discs and I never heard of a demo cominghere and for the 360. I think one of the staff would've announced that if that were the case. But like everyone knows multi- disc is inferior in the fact that the odds of having a defective or scratched disc is increased. I am well aware the same thing could happen with a blu ray disc, but its's more scratch resistant and it could be highly frustrating playing a game halfway through to only find out that the 3rd disc is scratched.
This is almost guranteed for frustration if you buy it used too.
I dislike the multi-disc and that is the reason why I have 4 copies of Final Fantasy IX and two of VIII. I don't have any multiple copies of any of the PS2 generation FFs.
