Looking for good PC base building games on Steam? The Steam Store can be frustrating to browse, as it's often a little too gratuitous with its tagging system. That's why we're ranking all the best base building games on Steam.

They Are Billions is a strategic base building game by Numantian Games, set in the future on a post-apocalyptic planet where the objective is to build and defend new colonies. Players also must try and survive against the billions of the infected who seek to wipe out the human race. In the sandbox adventure base building game Astroneer, the building takes place in outer space. Astroneer players colonize planets, erect buildings and infrastructure, and gather resources.
