Life on Mars [SOLD]
 

A strategy game based on Mars, in a similar regard to SimCity. I'm not entirely sure on its position on being abandonware though.
This is a link to the shareware version: http://games.softpedia.com/get/Share...-on-Mars.shtml

I hope it can be an addition.

Last updated 2011. Still sold far as we can tell.

That's fair enough then. All is well.
