Space engineers is a fantastic and atmospheric base builder and exploration game. The ability to create your own land rovers and space ships is at the core of the gameplay and through design iterations your vehicles will improve. The game has a steep learning curve and I would recommend using the wiki for reference.

Perhaps my favorite game of all time.

Complete ♥♥♥♥. The first mission has killed this game. VERY SHALLOW! One button controls should not be on the steam marketplace.
