I'm with R.Kyra on this one, getting everything in this game takes well over 100 hours if done properly.

I remember being at around 108 hours while still at The Pharos at Ridorana and that was before the battle with Cid. Completing only the storyline probably wouldn't take much time to do because it's relatively short but I've never done a speed run and my XII disc is faulty so I won't be able to try for a while now.
