I'll say FFI because the storyline (or lack thereof) wasn't too horribly engrossing. Or present.

And as far as the Tactics argument is concerned, this is all you need to know to be able to beat the game that's different from other Final Fantasy games:

JP is used to buy skills.
Skills are used to beat down enemies.
Red dots are places where you will fight and progress the storyline.
Green dots allow you to level up more by fighting in random battles.
Blue dots often let you buy things.
Jobs have different abilities and can be customized to your liking.
Move around the battlefield in order to attack people.
Spell radius is outlined in green when you are about to cast it.
The chance to hit percentage and damage that you will deal is at the bottom of the screen before you execute an attack.
Press left over a spell you want to cast to access the order of turns and see when it will go off.

Really, even that may be more than you need to know that cannot be figured out by a mentally deficient monkey. Tactics is an awesome game, you people know not what you do.
