As much as I hate Squeenix for the FFVI ports, I gotta say that the enemy and boss sprites look awesome.
That's the tower of gods according to the wiki
Keep in mind Japan isn't much religious to begin with, and Shintoism is also polytheistic. In other words they mostly don't see god as an all powerful being the same way your concept of good might appear to you.
I get that. It's been a while since I've played FFVI but why does Kefka decide to have his spine turn into a giant party pad for his friends that don't even help in the fight?
