I started a series called Planet city. I plan to post every day. The first save in the series is  with a desert, a beach, 2 big cities, 2 giant cave systems, a small underground city, a DEUT distiller, a DEUT reactor, a gold vault, and a giant tree. The second save is of the moon which has a moon base accompanying 4 people. The third save which will be of the equivalent of mars.
