Confession:
I liked the story of Final Fantasy Tactics Advance. I didn't mind that it was about kids. I didn't mind the quest system. I liked the new jobs.
But:
The quest system is something I think a lot of SRPG should have. In FFT, the propositions should have let you fight battles, for example. The quest system shouldn't be the only thing going on in the game though.
The jobs system was ok, but it seemed so unbalanced at how quickly new abilities are unlocked. It's like, you fight the first couple of battles and can only get 3 or so abilities, then after the fifth battle, suddenly nearly every weapon in the entire game is unlocked at the store.
The art style is terrible, and remains so in FFTA2.
The judges are awful, and not in the "THE LAWS ARE SO UNFAIR I HATES IT" way. No, the problem I had was that they destroyed my suspension of disbelief. Yeah yeah, WHY DO I CARE ABOUT REALISM IN A GAME WHERE TINY BEAR-BATS FIRE CANNONS AT ONE ANOTHER??? I don't mind any of the RPG schtick (HAR HAR THEY ALL STAND IN PLACE DURING BATTLE AND TAKE TURNS WHAT'S THAT ABOUT???), but the appearance of omnipotent beings on the battle field at every battle to make sure everyone follows the rules? That's too much for me. It ruined the feel of the game because it is just that stupid of a concept.
