I like this game's deep customization about the class, races, equipment, abilities & shops.
However, what is missing is the lack of difficulty in battle, long boring battle. Damn those characters, they move so slow, attack so slow.
I like the zodiac compatibility system in PSone FFT, as well as the wait-for-several-turns-for-magic-to-be-casted system. And in FFTA2, arrows can went through wall, what the hell. I also hate FFTA2 for almost 100% accuracy of every attack & magic no matter which direction you are attacking the enemy...
