Much of the praise heaped on the PlayStation version was related to its story, and it is indeed impressive.
Travel is via two different scales a city and world-map view.
It looks weird the characters literally jump into one body before moving, and hop out at other points but it works. Inc. The story starts in the floating city of Midgar and quickly mushrooms to encompass the entire planet and a dizzying array of subplots. Before the end of the game the player will have met multiple characters, each with their own detailed background, that properly positions them within the context of the larger story. Most of the crucial plot elements are told via long and beautiful three-dimensional rendered movies. Unfortunately, the actual presentation of these stunning visuals appears slightly distorted, but does not detract from the story.
