Took me probably about 70 hrs (my file is at 65:57 just prior to the final battle).
There's not much I can say good about this game, but it wasn't awful. I don't like the junctioning system. I'm not a fan of having no equipment to buy, just upgrading weapons. I ended up with about 1.5M Gil and spent maybe 50k throughout the whole game (and 99% of that was at the Ultima draw point in Shumi Village). The level-scaling monsters removed almost all incentive to fight random battles. I'm really starting to despise the ATB system, since battles turn into watching bars fill up. Too many long stretches of doing nothing but running around towns, talking to people, to where I felt like I was reading a book or watching a movie instead of playing a game. I know I missed a ton of optional stuff, but I didn't start following a walkthrough until the boss rush that is disc 4. I didn't even encounter a chocobo.
