The PC version with the higher resolution looks much much better. Though the actual character models are the same the reduction in pixelation makes them look much, much better. They still look dated, but they don't look nearly as bad.

The pre-renders look quite simply amazing still. Every time I play a PSX FF I can't help but think that that backgrounds are so much more prominent than in newer titles. I think this might also have something to do with the fact that there is no need for a minimap or hud of any type though.
