I was in middle school when I finished it for the first time. Absolutely brilliant game, with a story that's really well executed, epic music (that's on the duh files) and a gameplay that didn't make you wanna rip your hair out. (FFIV I look at you)
The opera part was what stood out the most for me, along with Leo's talk with Terra on the ship (and then Shadow's wise muses..and then Locke vomitblocking but I digress) for some reason.

What can I say? Great game with a simple yet elegant ending.
