The first FF I ever played was FF 8. But I only played it a little bit (I didn't have the game, it was my uncle's), then I bought FF 7. So FF 7 was the first FF I really played. ^^
Then I played 8, then 9, then a little bit of 1, 2, 4 and 5 (on PS), then 10, then 6, then 12, then 3 (DS), 13 ... If I remember correctly.

My favorites are 4, 4: TAY, 12 and 13. ♥
