As far as I know there's only one, and that would be FF Tactics: Advanced. I've played some of it, and read a lot about it, and it's a very good game. If you liked FFT, then you'd like this one.
yeah final fantasy tactics advance is great! i have it and im only up to 8th mission out of 300 and i been playin for 6 hours. very long and VERY VERY fun! but i dont really have time for it now that i have FFXI :P but if i didnt have access to FFXI i would be playinf tactics advance non-stop!
