Sol 0 is a Mars colonization RTS/small scale city building game that takes place in the near future, using technology that could be possible in a few decades. You need to balance power, water, food, and oxygen, as well as explore and mine resources with Mars rovers, and survive meteorite impacts and dust storms.
It is available on PC, Mac, and Linux currently for 2.99.
I would definitely be interested in doing a complete 'Let's Play' series if there is enough interest.
