After finishing the game today I can safely question this statement. 7 pics for finishing the game? WTF? Utter nonsense. I seriously doubt you finished the game. Unless the Xbox version didn't had an ending.
I clocked 65 hours until the ending. I spent about 30 hours on the last 3 chapters since I kept doing sidequests. And I had fun.
The start was quite annoying with no freedom on who to use... but when I finally got my freedom I did quite enjoy the ride.
Currently im farming Adamtoises for CP, Gil and Items. The fucker has over 5 million HP and hits for 7000 for each stomp. Vanille does wonders on this fight. She can kill it in 2 minutes maximum... if not... she's dead. LOL.
I got 49% of trophies as well.
