7 had a really good storyline but the way the story is told has been improved as the games gone on, and also the graphics.

My theory is the 1st FF you play tends to be your faviorite because it is what captured you into the FF series. This is why many tend to think 7 is the best because it is the 1st 1 they played.

i know in my case this is true, 8 was the 1st i played and it has since been my faviorite, probley because its what 1st captured me.

but maybe i'm wrong
