Moon and another attributes of the real Earth. Why?

Then the OP needs to convey their thoughts better. And you are not the thought police.

The thing about Zodiark being a dead god of a dead world got me thinking. Someone else may have brought something like this up before, but I got an idea. Hades was a summons in FFVII. One of my faves too, I might add. How about a dungeon based off of Tartarus? Hades could be a boss you have to beat to get to it. I'm not sure what/who would be inside though. Maybe shades of Zodiark? Like pieces of him that are lingering or something? I dunno, but the idea of a maze-like dungeon with puzzles would be fun. Sorry to go off-topic.

Was it really hard to create the really unusual world, but not the COPY OF THE EARTH?

The land is literally called EORZEA. It's supposed to be like Earth.
