Space Station Sim is a simulation game set on the International Space Station.
The player takes on the role of Mission Control, giving orders to the station
crew, and overseeing the completion of various missions. The astronauts have a
wide variety of tasks they can perform, including (but not limited to)
research, repair, exercise, eating, and enjoying themselves.

In addition to keeping the station running smoothly, the player must ensure
both the physical and mental health of the station crew. To support the crew,
the player can launch supplies, experiments, internal components, and new
modules for the space station. The player can also rotate crew on and off of
the station, as necessary.

The game allows customization of the station (through components and modules),
astronaut skills, and astronaut appearance.
