If you've never played a turn-based, tactical RPG, this is not for you. If you don't like limitless statistics, abilities, and customization of character classes and abilities, this is also not for you.
I'm not a fan of all the cutesy graphics, but that's a small price to pay for one of the deepest, richest, most complex turn-based strategy-RPGs ever written. You can easily get 100+ hours out of this, carefully building your small army of characters, tweaking and tuning their combat (and even non-combat) skills.
Try it at GameFly, then buy a copy. (Don't mind the ~30mins of tutorial and useless intro/plot -- it's wide open after that, and the combat is immensely satisfying.)
Generally I love Final Fantasy Tactics. I've spent countless hours playing them. This is a pathetic miserable excuse for a game bearing FFT, and square enix's name. First little obnoxious trait. There's a judge. You break the rules, you lose some nice abilities. Generally it's pretty easy to not break the rules, unless it's something fantabulous like, no damage over 50, and your average hit is in the mid 70's... Or my personal favorite... No distance targeting... Be sure to take the time to put one of your people behind whatever it is you're attacking, because if you crit it, and it flies, you lose. This is by far the most obnoxious part of this game. When you are working on improving your clan, you fail, you get to go back and spend more currency to try again, and again, and again, and you've got 4 turns to kill them all, and the end of the fourth turn your warrior crits them again, and they go flying, and... If you enjoy exercises in Futility, and being thoroughly annoyed at stupid things like that... don't let this review stop you. But better bang for your buck, PS1 FFT. Honestly, I am disgusted that this ever passed beta testing.
If it had been done right, I'd be singing praises. I usually get games that make me think, strategy type stuff. This Brings a lot of really neat features to the table, except I usually enjoy relaxing when I play a game, not getting frustrated at all the little things that were poorly implemented.
Save yourself the frustration, get something else.
