Final Fantasy Tactics is an incredible accomplishment.  While bearing the Final Fantasy name, it is not part of the main numbered series.  Final Fantasy Tactics brings a new style of gameplay to the Final Fantasy series: strategy.  This is a strategy game.  The goal of Tactics is not so much to explore the world, but rather to strategically win battles to advance the story.  The only exploration comes in finding where the best place on the battlefield is to put your characters in order to attack the most effectively.  This is a difficult game to get into at first, but given the chance the game becomes very addictive and soon may be one of your favorite games.  It is that good.
