My favorite is definitely Final Fantasy III (or FF6, depending on the continent). Honestly, next to Earthbound it's my favorite game ever.
I absolutely loved Final Fantasy VII, which I remember playing on my brand new Playstation when that was a brand new thing. It took so long to load, and it was on 7 discs I believe. I also played 8, 9 and 10, of which 10 was my favorite, but none were as good as 7.
Now that I'm into games again, I hope to have a chance to play the newer ones. Thanks for the stroll down memory lane! -Chris
