I played FFIV first, but didn't finish it because I got bored on my way to the final boss (though I always thought Rydia was awesome). Then FFVII, and didn't finish it because (this is not a spoiler, just what happened to me) Cloud opted to switch sides in the final fight and kill everyone, then himself. I was demoralized, so I didn't try again. I did like the game a lot, though. Then I played FFVI, and finished it. I absolutely loved that game, so it's the one that truly got me hooked on FF. Then I finished VIII, and loved that one too. My favorite would have to be a toss up between VI and VIII. I'm on IX now.
