Man, out of the whole game? Pft, dunno to be honest, there's too many to count. I mean how can you choose when you've got such iconic scenes such as Cloud jumping off the train, the reactor blowing up, Aeris selling a flower, the chase through the train, the fall into the slums, the climb over the garbage, cross-dressing, the Don's burlesque house, the destruction of the pillar, the Shinra building, the first sighting of Jenova, the Bike chase, the backstory flashback, the Midgar Zolom, meeting Yuffie, dressing up as a soldier, the ship ride, the climb across the mountains, the Golden Saucer jail, the broken reactor, the cave of the Gi, finding Nibelheim rebuilt, the Tiny Bronco crashing into the sea, the Temple of the Ancients shrinking, Cloud going mental, the Death of Aeries, and the Burial of Aeris? That's just the first disc for crying out loud!
