Of Life and Land is a newly released base- and city-building game on Steam, featuring familiar resource management, trading, and economic mechanics but with a realistically sinister twist. As you grow and develop your city, the world around you will start to change, potentially leading to mass extinctions, population booms, or ecosystem collapse if the natural order is disrupted too much. Of Life and Land only recently launched, but there is a 40% discount and a free Steam demo available.
