Playstation Store would be the easiest assuming you had a PS3 otherwise I would try sites that may have old title but isn't run by people in the knowing.

I felt it was an awesome game, almost an RPG version of Metal Gear set in Ivalice. I loved combat and Ashley and Sydney are some of the best protagonist/antagonist in any JRPG. Still waiting for that sequel but with Matsuno no longer at SE, I can't say how I would feel about a sequel without him.

I'm still hoping one of the FFT titles will have Riskbreaker as a job class.
