As much as FFXII holds a special place in my memories, FFX was the last game to give me that Final Fantasy feel. Crazy it's been over 12 years...

It wasn't a launch title, but this was the game that really set off the PS2 generation. That opening, fighting the Sin spawn on the highway was just... wow.

You mentioned Yunalesca, I thought it was interesting how, and I didn't realize it until I played it years later, her boss fight was a throwback to Cloud of Darkness from FFIII. What can be said, this game had class, people!
