How did they make the graphics of FF7: Advent Children?

I know it’s ridiculously complicated and 3d engine mumbo jumbo, but I’m just curious how Square is consistently able to make better computer generated graphics than anyone else.

If you have any idea about what programs/languages they used, I’d like to know and start practicing.

I want characters designed like those, but not a movie or anything… for a web-based game.

Thanks guys. Love ur site. The tutorials are really helpful and I hope to become a decent member here (have already started designing my pixel person).
