It would be easier to say

I DON'T own:
FF I & II on Wonderswan or SNES, but on PS and GBA.
FFIII, in any form (UK launch for DS version is a few weeks away)
FFIV-VI on the SNES
FFVII DoC yet
FFX yet
FFT on the PS

Otherwise, yeah it's all here. That includes FF Adventure, Mystic Quest and the Legend games.
