It's been way too long since I've played the game to remember what happened on what disc. I want to say disc one was my favorite though. I just loved the tone of that disc and how it set up the rest of the game. I also just really love the opening in general with the I Want to be Your Canary play and that short part where Zidane is trying to win the favor of the audience with his fight with Blank. There was just something so satisfying about the clang of the swords and hearing the cheers of the audience in that scene.
