Final Fantasy VI is and always will be my favorite game. It was the first game to really capture my short attention span for a long time and had me ignoring nearly every other game I owned for months and months. FFVI just had an amazing combination of great story, music, and characers all built upon some of the nicest visuals ever to grace the Super Nintendo. Square somehow managed to have far more characters then almost every other FF game out there, but still in my opinion developed them far more then other games in the series.
I did eventually play the somewhat flawed PlayStation port, primarily because of the nice bonus features (3 FMV sequences showing some of the SNES visuals converted into CG), as well as a slew of DVD like bonus features. Finally though there was a very refined version of the game released on the GBA with some new content, some translation errors fixed and far quicker load times then the slow PSOne disc had to offer.
