Haemimont Games brought you Tropico 4 and 5, among other games, although it is not doing Tropico 6. And Paradox Interactive is, well, Paradox, and has brought you Hearts of Iron and Crusader Kings II and, probably most applicable, Cities: Skylines, plus bunches of others.
Here's the main Steam page blurb:
There are also two other versions, Digital Deluxe Edition which has a few more bells and whistles and the First Colony Edition, which adds a season pass.Colonize Mars and discover her secrets, with minimal casualties.
Welcome Home! The time has come to stake your claim on the Red Planet and build the first functioning human colonies on Mars! All you need are supplies, oxygen, decades of training, experience with sandstorms, and a can-do attitude to discover the purpose of those weird black cubes that appeared out of nowhere. With a bit of sprucing up, this place is going to be awesome!
Surviving Mars is a sci-fi city builder all about colonizing Mars and surviving the process. Choose a space agency for resources and financial support before determining a location for your colony. Build domes and infrastructure, research new possibilities and utilize drones to unlock more elaborate ways to shape and expand your settlement. Cultivate your own food, mine minerals or just relax by the bar after a hard day’s work. Most important of all, though, is keeping your colonists alive. Not an easy task on a strange new planet.
There will be challenges to overcome. Execute your strategy and improve your colony’s chances of survival while unlocking the mysteries of this alien world. Are you ready? Mars is waiting for you.
I've tried to not spoil myself for the game by watching a bunch of previews, since heck, I know I'm going to get the game on release day pretty much no matter what; the things I do for you people . There is a short fifteen minute video by Scott Manley that loads up a few saves that give a nice idea about how a colony looks later in the game. I've taken a few peeks at other videos and the game looks reasonably complex enough to provide some hours of gameplay but doesn't look like a spreadsheet game, for which I am too damn old.
As I said, I'll be pre-ordering this game and posting impressions, so check out this thread in another week.
