I bought FFIII as well, it was fun but it did get tedious leveling up, and it could of done with a way to save in the the final dungeon because having to save outside of the crystal tower, work your way up about 6+ levels, defeat 4 bosses and then have to beat the second hardest boss of the game (There is a hidden boss that is harder then the final boss) is asking a bit too much. The job system is what got one of my friends hooked on it, he was forever starting again, picking new jobs for them to start with, doing his best to get an advantage.
I think they will end up remaking more of the final fantasies, though VI woud probably be the last one. I'm looking forward to the new Kingdom Hearts DS game 362/2 (or something to that effect)
