What Final Fantasy Tactics Advance did to the FFT name is disgraceful beyond words. Take four kids, let them play with snowballs in the town, then they get a magic book, and go into a fantasy world. While most of the kids enjoy their life in the land of Ivalice, one kid is upset that he is in a land he doesn't belong in. Thus, he goes on his one-dimensional quest to find his friends and bring them back to reality. 1 kid talks about going back home, the others don't want to. That's the level of character development. The game was made to appeal to kids, perhaps in order to attract more money from its buyers. The soundtrack was composed to be catchy, ruining FFT's grounds of an epic score of music. As for the battle system, make it 1.5x slower, take away special moves from each class (like Toad, Poison, Flare, and Death for Black Mage) and put in their place the most useless, unnecessary classes you'll ever find in a game like this. Some of these classes are broken, to the point that it makes the game lose the rest of what little challenge it had.
In light of this disgrace to the original FFT, it is appopriate that, whenever a discussion of FFTA ensues, anyone who realized this can say, "Lol FFTA", mocking the little effort that went into the game for its complete inability to live up to its prequel.
"Lol FFTA. Play the original."
