Which is Your Favorite Game In The Final Fantasy Series?

Hi guys, in the Final Fantasy series, which was your favorite game and why? For me, I especially loved the fourth game, it has a great story.

I know this thread is old but...

I would say Final Fantasy 10. I really like playing it No sphere grid challenge. So you only have attack, overdrives, aeons, and starting abilitys such as wakka's dark attack. Makes the game a fun challenge.
