That's a good strong point. Let's not forget in the game their world is called Earth, and the galaxy is the same as ours. So you might be on to something. Actually I think if you look at Final Fantasy, Spirits within, you'll see the true start of it all!

You know, this is the first really interesting essay I've read in a ong time. Excellent. The crystal skull thing sounded cool, I'll look into that. Praise for you!

Peace!

While it's probably true as you mentioned that FFVII probably had the Earth in mind, this was a good assessment.

As for the skulls, how peculiar.
