I originally thought that V was my first FF game until I found an old FF1 cartridge amongst a stack of other Japanese NES games in my aunt's place. I was only 4 or 5 years old when my parents used to leave me there to play while they're at work. I played all of the numbered ones but managed to complete only a few. First FF I finished was V (used a guide since I didn't know Nihongo back then, fell in love with the job system), then VII, Tactics, VIII, IX, and VI. I played FFXI for a short while but only got to mid-level range on a few classes before I joined my friends in MMO-hopping. Tactics is my favorite and the one I played the most, especially its update - War of the Lions. I had the original on PSX, then WotL on PSP, and finally the iOS version. I played XIV 1.0 for a short while getting to level 30+ on a couple of classes before I quit and played a different MMO. 2.0 is decent and somewhat reminds me of XII's gameplay.
