1) FFVI (awesome OST, awesome everything, you can let your friends control some party members on pad2)
2) FF Tactics ((love the story, also loved Ogre Tactics on super famicom)
3) FF VII had lots of charm
4) FFiV old school
5) FF IX

I played all final fantasy titles except the one for the mobile and Chocobo dungeons.
Didn’t like Chrystal Chronicles so much and didn’t like the FF Tactics defender on iphone.
Was disappointed where FF Tactics went with A1 and A2… awesome story replaced with 2grader kids…
With FF X-2 I started to lose interest with the series.
I pray for a nice Remake of FFVI for DS.
