I have played FF1, FF1 Advance, FF2, FF2 Advance, FF3 (ds version), FF4, FF4 Advance, FF5, FF6, FF7, FF8, FF9, FF10, FF12, FF Crystal Chronicles, FF Mystic quest and FF Tactics (That gameboy version)

I think FF 3 and FF 5 are awesome becouse they have the job system.

Ive played 2 for gba,4,6,7 crisis core, 9 and tactics

i have played all the FF games =P and my Fav is FF5 i love how the Jobs worked you leveled the jobs and your chars so one char can be a level 5 knight and a level 2 white mage two
