You're on an alien planet (top down view). You have a few supplies. You need to mine (on the surface) and transport resources to be turned into supplies which can then be used to make other things. The planet though has native animal life on it and they get annoyed when your pollution reaches them. Basically you're managing supply chains. If you plan poorly things grind to a halt.
It's beta or alpha at the moment but it's pretty damn good and it's not just a copy of every other game out there.
