As I recently played the consol classic for the 4th time ( love it to pieces) I have to say Im split between two favourite moments.
1. The FMV sequence when the Weapon attacks Junon Harbour and all the Shinra and coastal defences fire at it , eventully with that huge cannon blowing its head off.
2. Fighting the final sephiroth and crapping my pants when his Summon was that metor one where it shows the plants being ripped apart by his his hige metor.
Classic game and always will be. I advise anyone who hasnt got the game to get it as the storyline is ahead of our time in quality.
