(SPOILER)In Final Fantasy Tactics, isn't the ultimate bad guy prettymuch Jesus? I mean, the plot of Final Fantasy Tactics is to reveal that the church is actually rather demonic, and not holy at all, and their patron saint is evil, and incidently, named after a model of Nissan.

I don't think that FFTA had a villain named Tercel or Impreza.

I do agree that FFTA isn't a classic children's story. In fact, it's a story that most chilren would not want to hear. The characters are children, but that doesn't make it a childish story.

However, comparing the central plot of FFTA to that of FFT, it becomes apparent that if you were to try and explain either scenario to a child, you'd have more luck with FFTA. Imagine trying to unwind the simple details of Ivalice after the 50 years war. And then factor in the appearence of Lucavi and eventual descent into 'hell'. It's a lot more complex than a boy's imagination becoming reality and taking over the world.
