The planet Mars hasn't changed since my first post. Maybe you just thought the planet called Haaigon was Mars because it look more like it. Well, actually, it is Mars, un-terraformed, "borrowed" straight off the net and given a planet-spanning megalopolis.

The Mars that is the actual Mars is also "borrowed", if you will, from this thread, with a bit of retouching done, and a cloud pattern added. Whether it is based on the actual geography of Mars, I cannot tell.
