Not true. There is one thing left to do after defeating optional bosses, getting level 99 on everyone, maxing up all stats, getting all level four limit breaks, getting three mastered materia of each kind (one for each character), and getting the gold chocobo. There is only one thing left to do at the point.

It will ultimately prove that you have mastered the game and that you have no life. I sadly must admit that I am currently in the undertaking of this task. To master the game, you must max out experience. I'm not entirley certain if this is possible, but I'm going to try. Right now I'm pretty high. Haven't played it in a while though, so I couldn't say where I am exactly. Somewhere in the 4 millions I think (or is it 40 millions. Dont' remember).
