I had the import of this game, and it is excellent. The world is in chaos, but not quite like it is in every other RPG. The world basically folds in on itself so that everything exists on the inside of the earth. You can also communicate with demons in battle instead of fighting, and they may ask you questions, or demand bribes to either leave you alone or join with you.
Most interestingly of all, you can choose how to rebuild the world (broadly) as either a world of anarchy, law and order, or a couple other philosophies. It also has an interesting background and presents the many deities of the world in interesting ways (including Yehova and Lucifer!)
