Final Fantasy 8.
I enjoyed the story... And the visuals to me felt more impactful over Final Fantasy 7's character design or the regression I personally perceived in Final Fantasy 9 character design.
The seamless transition from gameplay to FMV was just icing on the cake back then and was seriously impressive.
To be fair though, I never played many games outside of FF8 on the PS1, I was strictly PC at the time... Something to be said about having a Voodoo 2 instead of the PS1 blocky visuals or the Nintendo 64's blurry Vaseline output.
Though the JRPG's on the console did interest me.
