No contest, FFT.

That game changed my life. It changed the way I play video games. I liked FFTA, but it wasn't what I was expecting and was just a little bit too different from the original. The story in FFTA was awesome, but it was pretty simple, compared to FFT.

FFT has the most interesting story full of betrayals and questions with a final resolution for most questions by the time you beat the game. Every character has such depth and a backstory that you can read at your pleasure.

The only thing I found in FFTA that was really amazing was the Combo system. I liked that. It would've been cool to have a system where two or more characters could combo off of one another in battle in the original FFT.
