The Final Fantasy IX ending for me. Another scene I especially remember is (SPOILER)Cloud vs. Bahamut in FFVII AC.

Jowy: Isn't that the fight on Chapter 2 with the "Battle on the Bridge" music playing in the background? It's a great heroic song that uses Ramza's theme too. I somehow remember that scene, and it was a pretty powerful scene, although I thought the (SPOILER)Golgorland Execution Site battle was even more intense.
