...what would happen if an ocean appeared on Mars? addon - Have you ever thought...? mod for Ages of Conflict

What if, somewhere else, a civilization similar to ours had arisen? What would that world look like? I will try to create maps of other planets and alternative worlds, but I will only ask you to try and experiment, painting them in accordance with my ideas about where it would be good to live on the planet. I hope I don't disappoint.
