Final Fantasy 3 US (6). Wasn't my first game, however. As a kid, it was just an incredible world to experience, that blended steampunk and fantasy nicely, had some quirky characters, and a soundtrack that I can hum in my head to this day when I think of parts. Everything about it was fun, from basic fights, to the larger battles / dungeons that made you assemble 2 or 3 full groups, stomping over enemy soldiers in Magi-Tek armor, to the midpoint cataclysm it's known for.
But, after playing it as an adult, I have to say the characters, while somewhat simple compared to modern games, and WRPGs, were far more poignant in their execution. Edgar and Sabin in particular stand out, because they remind me of my brother and I. My brother, the elder of us, is pretty much Edgar to a tee - an Engineer, dutiful, and most importantly understood the of family. He's the one who settled down, and gave my parents grandchildren. The prodigal son for lack of better words, while I'm sitting here typing about video games, valuing my freedom and wanting nothing but to lift. And he has never given me grief for it, if anything, supporting my decision to be left alone, and pursue something else, whatever it may be.
