I thought the world of X was quite impressive. I like it's take on technology, Don't touch it, don't look at it, don't even think about touching it or looking at it, or Sin'll get you! I really thought that was interesting. It felt like it was trying to break away from the continuity of the series. Usually the technology and the magic is coexisting, like without one the other would be unattainable, but in X they're warring with each other.

Whenever I think of VII, I think of the Dark Ages. The way the world is reminds me of what I heard about the Dark Ages in the third grade. The Planet has seen happier times, but we don't know them. All we know is the barren soil surrounding the Mako Reactors and the the iron fist of Shin-Ra.

Also, IX had the first real feel of an FF game in a long time. Don't get me wrong, I love VII and VIII, but IX was something else. I really don't know how to explain it. The feel of the world was something I hadn't felt since VI.
