Final Fantasy 7
The first game in the Final Fantasy series to leaved the Nintendo console and the creation of "cut-scenes" (scenes where heavy computer graphics help embellish the story-line).  This book is also inside of the Guiness Book of World records for its incredible sales.

Many people call this game over-rated.  It's not over-rated, people are just sick of hearing how good it is or just rebels with a cause to start frivolous arguments.  If people come past that they'll acknowledge how the side quests (adventures the party goes on that isn't a requirement of completing the game) really help garnish the story.  In order to know the ENTIRE story, the side quests must be completed.  Though the side quests are nearly infinite, it's a fantastic way for Final Fantasy gamers to know the entire history behind EACH character.  This is rare in RPGs since the minority party members are usually in the background and nothing to help embellish their character.  

Final Fantasy VII is arguibly the best game in it's class.  Paying attention to the story-line and not negative comments on this will tell you this.
