Well, I had picked up a copy some time ago, Friday (071012.5x to be exact). I have played it, and of course, it is pretty much a mirror image of the PS1 version, except the FMV is more cartoonish like, and there are some upper function things that are different, such as some new job classes, an extention to the story line, and multiplayer abilities. Also, there are some FMV's that have replaced some text conversations, and actual voice over in the FMV.
I am really looking forward to the multiplayer mode, however, in order to do that, I have to find someone else with a PSP and local to the area. I am dissipointed that only Ad Hoc mode is supported for multiplayer. So now I actually have to track people down, for there is also no game download support (meaning both parties have to have a disc). It also would have been extremely nice to see a larger multiplayer other than two player mode.
Anyone who has a PSP and would be interested in getting the game, let me know, as the multiplayer mode will unlock things you cannot get in single player.
