SpaceStationSim is budget title that you can freely take at face value. Its mission statement can be entirely inferred from its title: A true to life re-creation of maintaining a space station - which, as it happens, resembles a cramped college chemistry lab way more than it does the interstellar mechanized death-moon from Star Wars - and a slight rip-off of The Sims.
Whether or not the gameplay itself will set your world on fire depends on just how many times you've been to Space Camp. You're charged with the upkeep of an orbiting satellite and all its equipment and crew. No matter how minute the detail, everything must be tended to otherwise your crew could mutiny, and you'll wind up with your tainted name emblazoned across newspapers. Scandalous.
Houston, we have a problem... a humidity problem? In SSS you'll have to manage even the most mundane of details - including zooming (probably not a NASA sanctioned term) back to earth to pick up a humidifier using currency accumulated amongst NASA and other space-faring nations. You can then order your astronauts to activating said humidifiers, as well as repairing CO2 scrubbers, performing science experiments and even use the space toilet (Visual Conformation Denied! The world may never know how to pee in zero G.)
