In order...

FF2US (SNES)--awesome
FFMQ--not bad, but not exceptional either
FF3US (SNES)--greatest game I've ever played, by far
...(long time passes...I eventually buy a PSX so I can play the entire series, starting, of course, with IV and VI again...the rest were all mingled together throughout the next year and a half or so)...
FFIV
FFVI
FFVII--extremely disappointing...I wouldn't call it bad, but I certainly wouldn't call it good, and definitely not what it's made out to be
Chrono Trigger--pretty good
FFT--pretty good, although difficult
FFV--different system than I was used to, but good
FFII--not bad, just...very different
FFI--gives me that warm fuzzy feeling inside, playing the one that started it all
FFVIII--not too terribly bad...but definitely not too good
Chrono Cross--again, disappointment, but not nearly as severe...not an extremely bad game
FFIX--not bad, just...interesting

If I'd have to rank them best to worst, they would be 6-4-1-Tactics-5-2-7-9-8
