I´ve never played FFI and I really doubt I will ever bother playing it.
I also love FFT and Vagrant Story, I don´t like FFTA much, I dislike the FFCC series so far, FFVII: DoC is so-so, I liked FFVII: AC. Haven´t played FF Mystic Quest (it´s not FF to begin with) and never will. I will soon play FFVII: Crisis Core.
