Just beat Persona 3 with a mere 112 hours on the game clock
If I'm not mistaken that is the longest RPG I've played to date. I can't rave enough about this game. Great story, great characters, nice challenge. You do break the game once you get Lucifer and Satan though since they have an unblockable combo attack that does max damage.
I hope the Persona 3: FES side story comes to North America, I didn't want the game to end.
