As a 28 year old man being able to play games I grew up to is captivating. FF3 raised me.  With out being dramatic I will say as an impressionable young boy who was a year round athlete and student I still had to set time aside (too much according to my mother) to purchase a case of mountain dew and spend an evening leveling my characters.  I think this is ubiquitous for most avid gamers but what I believe this game gave me that is unique is my own character.  I was in love with the story line to start, passionate heroes and menacing antagonists, plots and counter plots forks in the road and remote challenges as we all know is common now but back then..........lol I used to sleep with a plastic ax and dream  I was an esper. I digress and so what I meant by character was I took a little from most all of the ones in FF3.  Assertiveness and passion from Sabin, loyalty and devotion from Cyan, Arrogance and ingenuity from Edgar, street smarts and savvy from Locke, Duty and rational from Celes etc..... I even assimilated trouble and sadism from Kefka. Even through my teens you could compare my isolating habits or mood swings too shadow.  I know to embellish natural human development making it comprehensible to a video may seem immature but ill say as we model ourselves in society I personally see nothing wrong with learning human qualities from a make believe world. After all those of us who can say we've fallen in love with a game seem to capture a games essence with what its creators are trying to model about our real world.  FF3 I believe won awards for its soundtracks and any gamer who says they didn't water up when Cyan's family says for well on the ghost train is bs'in. There was a lot of drama in this game as well as creative plot twists which as a ten year old boy kept me a FF fan forever.
