I played a little bit of Final Fantasy 1 and 2, the Origin Remakes for ps 1 and they were fun, i also watched my sister play half of Final Fantasy 13 and it looked amazing and i also played dirge of ceberus for playstation 2 which was also fun.
I tried 1 and 2 but never made it very far, but I've played through or most of the way through 7, 8, 10, 10-2, a bit of 14, and Dirge of Cerberus. I have a soft spot for RPGs.
