In Polar Motion’s Space Station Designer, the goal is the construction of economically sustainable space stations that also produce science, just like the ISS. But they also have to generate enough electricity and dissipate the heat produced, in addition to having room to house the crew.
For this you have several modules, each with a price, a maintenance cost, a weight, energy needs and heat and crew dissipation.
In turn, each module can generate research, income and electricity points and offer heat dissipation capacity, space for crew and extra docking ports.
It is available for Mac OS and Windows in a free pre-alpha version, which developers expect fans to use to tinker and give them opinions in the face of the final version. It includes a tutorial and a mode of unlimited funds so that you learn the basic handling of the game before putting yourself to build real space stations.
