Disc 4? unnecessary? rubbish! Sure disc 4 was a little different to the story BUT it rapped things up! if it had been finished in memoria:
a. yes the story would have been rushed
b. it wouldn't have made much sense that Kuja became tranced and blew himself up!
c. It would be a black sheep in the line of Playstation games!
FF7 disc no.: 4
FF8 disc no.: 4
FF9 disc no.: 3

Even though i love FF9 and i REALLY wanted Zidane and Dagger/Garnet/Sarah to get together i still thought the ending was SO corny!!
^_^
Thats my only problem with the game, the ending ^_^
