While FFII certainly gets the honor of being the first FF to be story driven; I've always felt that FFIV was the first character driven piece in the series due to so much of the games drama and allure being the actual events that affect the characters as opposed to the high adventures of seeing new places or stopping evil. Others might argue the game was too simplistic for this, but I still feel that for its time frame FFIV did a fantastic job of introducing us to a wonderful cast of characters who made us a feel for them.
