I'm playing FFX At the moment. I'm loving the characters, and the story is pretty good overall, but the gameplay gets a bit tedious. The boss battles are awesome, but there are too many areas that are basically just long hallways where you fight the same 3 or 4 enemies over and over. Also, I wish that instead of your party healing at every save point, you could save more frequently but your party healed less often, meaning it would be much easier to run out of supplies, and you wouldn't have points where it's an hour to the next save point.

I'll probably try FFVII or FFIX once I beat FFX and FFX-2
