Well if you guys are going to state each FF you owned, briefly played,and beaten then i will too.

Own:
Final Fantasy I(Origins)
Final Fantasy II(Origins)
Final Fantasy IV(Chronicles)*got it today*
Final Fantasy V(Anthology)
Final Fantasy VI(Anthology)
Final Fantasy IX
Final Fantasy X
Final Fantasy Tatics Advanced

Beaten:
Final Fantasy I
Final Fantasy VII
Final Fantasy VIII
Final Fantasy IX
Final Fantasy X

Still playing:
Final Fantasy IV
Final Fantasy V
Final Fantasy VI
Final Fantasy II


And sadly i haven't purchased VII or VIII because I just kept borrowing it from my friend. Now it's kind of hard to buy two games that you wont be playing cause you've already played and beaten them twice while mastering them mostly.
