How good is the actual plot of the game. From what I remember the major chunk of ffVII was put into developing each of the main characters (which they did a very good job of). But when you take the characters out of the equation the actual plot of the game really sounds extremely basic. Avalanche destroys a couple reactors. They find out Sephiroth is loose and decide to start chasing him. They spend much of the rest of the game traveling from town to town finding things out about Sephiroth until at the end of the game they finally catch up to him and beat him.
When you think about it that is about the gist of the entire plot of the game. And when you think about most of all the good parts of the game take place while they are either developing a character in the present or developing a character through a flashback.
