For me it was Final Fantasy 9. The characters intrigued me, and it went back to its roots, with the medival style, the airships, and character design. The story was immersive and the graphics were one of the best on the Playstation I would say, and the cinema scenes were great. Though I would have rather had Kuja been my final villain, rather than turning good, and dealing with some force from beyond, who had no introduction until then in Necron. Still ya gotta take the bad with good, and vice versa.
