The best moment has to be... after playing the game for 100hrs+ over the span of 6 months, finally getting all the Ultimate Weapons for every character, completing every optional side quest, leveling up every character to its max, collecting everything there is to, chests ect...(list could keep going).... and then finally smacking the hell out of final boss and watching the ending movie, and all the credits, and the fantasy finally being done...tear... not being able to save again because the game is officially over...

Then finding out the nect FF installment comes out in a year, and you just cant wait to play..hee hee
